Smart Driving Cars episode 410- MIT Karl Iagnemma Forum, Artemis II, Waymo, Subaru, Tesla & more
About this episode
Alan Kornhouser and Fred Fishkin kick off with a Princeton/industry-style roundup that blends autonomy news with big-picture mobility history. They highlight an MIT mobility interview with Ekno Robotics CEO Carl Enyama, tracing autonomy from DARPA to robotaxis to warehouses. The discussion then pivots to Waymo’s rapid ridership growth, why vehicle occupancy math can be misleading, and the core challenge of repositioning. They also cover connected-vehicle V2X trials, Subaru’s hands-free Outback update, and a long, economics-focused argument that driverless trucking should boost driver productivity—not remove drivers. They close with an AI book recommendation and a planned ride-sharing road trip.
An MIT interview on the Full Arc of Autonomy, Artemis II, progress at Waymo, Subaru Outback goes hands free and a warm reception for the Tesla Semi. All that and more on episode 410 of Smart Driving Cars with Princeton's Alain Kornhauser and co-host Fred Fishkin. Tune in and subscribe!
autonomy
"you lead off with an MIT mobility interview with the CEO of Ekno Robotics, Carl Enyama, says from DARBA to Robotaxies to warehouses, the full arc of autonomy."
Autonomy means a system can make its own decisions—like how to move and navigate—without someone constantly steering it. In self-driving discussions, it’s the big idea behind getting from research to real use.
In this context, autonomy refers to vehicles or robots making driving or operational decisions without continuous human control. The discussion frames autonomy as a “full arc,” from early research to real-world deployments like fleets and warehouses.
Ekno Robotics
"you lead off with an MIT mobility interview with the CEO of Ekno Robotics, Carl Enyama,"
Ekno Robotics is the company being discussed in the MIT interview. The point is to learn what they’re building and how it relates to real autonomous systems.
Ekno Robotics is the company whose CEO is interviewed in the MIT mobility segment. In autonomy podcasts, company mentions matter because they often indicate a specific approach (robotics platforms, fleet operations, or warehouse automation) rather than just general theory.
Carl Enyama
"with the CEO of Ekno Robotics, Carl Enyama, says from DARBA to Robotaxies to warehouses, the full arc of autonomy."
Carl Enyama is the CEO being interviewed. His role matters because he can explain what his company is doing in self-driving and robotics.
Carl Enyama is identified as the CEO featured in the MIT mobility interview. For listeners, the CEO’s background can signal the company’s focus area within autonomy (e.g., robotics deployments across logistics and mobility).
MIT mobility interview
"you lead off with an MIT mobility interview with the CEO of Ekno Robotics, Carl Enyama,"
This is an interview tied to MIT and mobility, meaning transportation technology. It’s often about how self-driving ideas move from labs into real-world use.
An MIT mobility interview signals a focus on transportation technology and research-to-deployment pathways. In autonomy discussions, “mobility” usually includes both passenger transport (like ride-hailing) and operational logistics (like warehouses and fleets).
Robotaxies
"says from DARBA to Robotaxies to warehouses, the full arc of autonomy."
Robotaxies are self-driving cars that you can call like a taxi. Instead of a human driver, the car handles the driving.
“Robotaxies” are autonomous ride-hailing vehicles—think of a taxi service where the car drives itself. They’re a key milestone concept in self-driving because they require robust perception, planning, and safety across real urban conditions.
DARBA
"says from DARBA to Robotaxies to warehouses, the full arc of autonomy."
This likely refers to DARPA, a U.S. research agency that funds big technology projects. In self-driving, DARPA has historically supported early breakthroughs in robotics and autonomy.
“DARBA” appears to be a transcription error for “DARPA,” the U.S. Defense Advanced Research Projects Agency. DARPA is known for funding major autonomy and robotics programs that helped accelerate self-driving research.
Chapter 11 bankruptcy
"“Chapter 11, the chapter six, which means it's not just it's not just Wall Street or investors that get hurt. It's everybody because then you sell the assets, you tear up the tracks…”"
Chapter 11 is a legal process where a company tries to reorganize instead of shutting down right away. For railroads, that can mean big changes that affect service and jobs.
“Chapter 11” is a U.S. bankruptcy process focused on reorganizing a company rather than immediately liquidating it. In the context of railroads, it can lead to service changes, asset sales, and restructuring that affects both freight and passenger operations.
Conrail
"“The important date was April 1, 1976, when Conrail was formed… not only for the freight railroads… but also the passenger part.”"
Conrail was a company created to take over struggling railroad lines in the Northeast. It helped stabilize rail service after several other railroads went bankrupt.
Conrail (short for Consolidated Rail Corporation) was created in 1976 to take over major failing rail lines in the Northeast. The episode frames it as a key transition point for both freight and passenger rail service after multiple bankrupt railroads.
Penn Central
"“…the transition from Penn Central and the other six bankrupt railroads to Conrail was the transition that took place on April 1.”"
Penn Central was a major railroad that ended up failing. Its collapse is part of why new railroad structures like Conrail were created.
Penn Central was one of the largest U.S. railroads before it collapsed in the early 1970s, triggering a broader crisis in the rail industry. The transcript uses it as the starting point for the transition into Conrail.
Artemis II
"Talk about stirring up memories, Alan. Artemis II is carrying four astronauts around the moon and back. You've got a link. And for both of us..."
Artemis II is a NASA mission where astronauts will go around the Moon and return safely. It’s a step toward longer-term Moon missions.
Artemis II is NASA’s crewed lunar mission that will send astronauts around the Moon and back. It’s part of the Artemis program, which is aimed at establishing a sustainable human presence on the Moon.
Earthrise
"it was a big one simply because of the image that was the photograph that was taken of Earthrise over the moon, you know, in December 1968."
“Earthrise” is a famous picture of Earth appearing over the Moon. It’s iconic because it shows Earth from space in a really striking way.
“Earthrise” refers to the famous view of Earth rising above the lunar horizon, captured during the Apollo era. It became an iconic image because it showed Earth as a whole from space, influencing how people think about our planet.
Waymo
"What we're trying to do with driverless cars is I don't think political. It's just a value to, to society. Absolutely. From MSN, Waymo has doubled its weekly ridership in under a year."
Waymo is a company that builds self-driving technology and runs robotaxi rides for the public. When they talk about ridership, they mean how many paid trips their cars are doing.
Waymo is Alphabet’s autonomous-driving company that operates a commercial robotaxi service in select cities. The discussion here focuses on its ridership growth, which is a key real-world metric for how well driverless services are scaling.
driverless cars
"What we're trying to do with driverless cars is I don't think political. It's just a value to, to society. Absolutely."
Driverless cars are cars that can drive themselves using technology and software. The point here is that if they work well, they can provide real transportation benefits to people.
“Driverless cars” refers to vehicles that can operate without a human driver, typically using a combination of sensors, onboard computing, and autonomy software. In this segment, the speaker frames it as a societal value and ties it to measurable service growth (ridership).
paid rides
"Now it's up to like half a million paid rides a week. Yeah. I'm wondering why they're using a half a million per week, as opposed to a hundred thousand per day."
Paid rides mean real customers are paying for the trip, not just testing. That usually suggests the service is working well enough to be offered commercially.
“Paid rides” indicates commercial operation rather than free trials or internal testing. For autonomy companies, paid ridership is a stronger signal of real-world readiness because it requires reliability, customer trust, and consistent service delivery.
productivity (per vehicle)
"it indicates that they're probably doing, you know, 25 rides or so per vehicle or per day. And, you know, it's, that's pretty good productivity, especially when you, you know, basically everybody you give a ride to is by themselves."
Here, productivity means how many trips each self-driving car is able to do in a day. More trips per car generally means the service is running efficiently.
In the context of robotaxis, “productivity” typically means how many trips a vehicle can complete over a given time period. The speaker estimates rides per vehicle per day to interpret what the ridership numbers imply about operational throughput.
empty vehicle repositioning
"And the real value proposition of the driver list is empty vehicle reposition is to go from the last person you gave off, gave a ride to or per sons to the next person or per sons, you're going to give a ride to."
Sometimes a car has to drive to a different spot before it can pick someone up. That “empty” driving doesn’t carry passengers, so it’s important for the system’s efficiency.
Empty vehicle repositioning is when an autonomous or shared vehicle drives without a passenger to move to a better starting location for the next pickup. In mobility systems, this is a major source of wasted time and cost because the vehicle is operating but not generating passenger revenue.
parking
"So either you sit around and wait, which is what people do with their own cars. And therefore that's why you have parking."
Parking is basically leaving a car sitting until you need it. The speaker is saying that’s what people do with their own cars, while shared/automated systems try to avoid waiting by moving vehicles around.
“Parking” is used as an analogy for how conventional personal cars handle the same fundamental mismatch between where a vehicle is and where it’s needed. Instead of repositioning efficiently, personal cars often sit idle until the owner wants to use them.
Uber and Lyft
"But when we go over there and pick them up, which is really what Uber and Lyft do, except they have a person in there that needs to be paid for that."
Uber and Lyft are apps that connect riders with drivers. The comparison here is that they can keep rides flowing because there’s a real driver ready to pick someone up.
Uber and Lyft are ride-hailing platforms that match riders to drivers in real time. The speaker compares their model to autonomous mobility, noting that Uber/Lyft effectively handle the “next pickup” problem by having a human driver available to serve requests.
V2X
"From simply Wall Street, Alan, this might be a head scratcher. V2X Trial in Bordeaux, what's connected mobility story and focus?"
V2X means cars can “talk” to other cars and to things around the road, like signals or infrastructure. That communication can help with safety and smoother traffic.
V2X (vehicle-to-everything) is the umbrella term for communications between vehicles and other road users/infrastructure. The goal is to share safety and traffic information so vehicles can coordinate more efficiently than with sensors alone.
connected vehicles
"I mean, actually, it is. I hope it's only when I see it, there's nobody in there besides the driver... Anyway, and it talks about the demo ending... Anyway, trying to think that somebody is going, Mr. Trump is going to be out there controlling traffic with it because as information has to, because they're connected, you can organize everything for greatest efficiency in our roadway"
Connected vehicles are cars that can share information with other cars or with road systems. The hope is that traffic can run smoother and safer because everyone is “in the loop.”
Connected vehicles are cars that can exchange information with other vehicles and/or infrastructure. The speaker links this to the idea of coordinating traffic for “greatest efficiency,” implying a system-level approach rather than isolated vehicle behavior.
commodity
"Financial times as a report headlined, self-driving will not make Nissan a commodity, says CEO... Although one would like to do all this so that it is a commodity, so that everybody, commodities are things that everybody can have as opposed to luxuries..."
A “commodity” is something where buyers see no big difference between brands. The discussion is saying self-driving shouldn’t become that—companies want it to feel unique.
Calling self-driving a “commodity” means the technology would become standardized and interchangeable across companies, competing mainly on price. The speaker argues that automakers want differentiation so their systems aren’t treated like a generic product everyone can buy.
Nissan
"Financial times as a report headlined, self-driving will not make Nissan a commodity, says CEO."
Nissan is the car company being discussed. The point is that their self-driving strategy is supposed to be unique, not just a generic feature everyone has.
Nissan is the automaker referenced in the claim that self-driving won’t make the company’s offering a “commodity.” That implies Nissan’s approach to automation is meant to be differentiated rather than interchangeable.
self-driving
"Financial times as a report headlined, self-driving will not make Nissan a commodity, says CEO."
Self-driving means the car can do more of the driving work by itself. Usually a person still has to supervise, depending on the system.
In this context, “self-driving” refers to automated driving systems that can handle driving tasks with varying levels of human supervision. The discussion frames it as a differentiator for automakers rather than a commodity feature.
General Motors
"I mean, it's going to make. I think General Motors is not testing 200 vehicles. I guess they're back to going to make two."
General Motors is the automaker being discussed. The idea is that they tested a lot of cars, but then changed course—likely to improve results or focus their testing.
General Motors is mentioned as having tested a larger number of vehicles and then scaling back. In self-driving programs, the number of test vehicles often reflects how aggressively a company is validating safety, reliability, and edge cases.
hands-free driving
"gains hands-free driving for the first time. This is similar to what I think Ford and GM have, because it operates on interstate highways, at least some of them, many of them, and so it's a step that Subaru is taking now."
Hands-free driving means the car can help steer for you, especially on highways. You still have to pay attention because the system only works in certain situations.
Hands-free driving refers to driver-assistance systems that can control steering (and sometimes other functions) without the driver actively steering, typically within defined conditions like certain highway scenarios. Even when marketed as “hands-free,” these systems usually still require driver supervision and may disengage outside their operating domain.
Subaru
"and so it's a step that Subaru is taking now. Subaru claims that they're better too, so it's not only, it's even better than theirs."
Subaru is the automaker being discussed, and they’re known for safety-focused driver-assist features. The episode suggests Subaru has been improving these systems for years.
Subaru is highlighting its driver-assistance and safety technology as a differentiator, especially through its “EyeSight” system. In this segment, the host credits Subaru with strong performance in safety evaluations and positions the 2026 Outback’s feature set as a continuation of that approach.
EyeSight
"Their eyesight we've talked about in the past was fantastic. I mean, for years I would show their commercial that they made in like 2014, which basically promoted eyesight with this, you know, crash dummies and a crash test."
EyeSight is Subaru’s safety system that uses cameras to watch what’s happening ahead. It can help the car slow down or avoid crashes when it detects danger.
EyeSight is Subaru’s suite of camera-based driver-assistance technologies, commonly used for functions like adaptive cruise control and automatic emergency braking. The segment references Subaru’s long-running marketing and emphasizes that the system helps prevent crashes by reacting quickly and monitoring the road ahead.
standard equipment
"and here they are with this, and in the model they're offering it, it's standard equipment."
Standard equipment means you don’t have to pay extra to get the feature—it comes with the car. That can make safety tech more accessible.
“Standard equipment” means the feature is included on the base trim rather than being locked behind an expensive option package. That matters for hands-free and advanced safety tech because it affects how many buyers can access the technology without paying add-on costs.
between two white lines
"That doesn't mean they don't have to sit there and keep the darn thing between two white lines because technology is doing that."
It means the car can keep itself centered in the lane. Instead of the driver constantly correcting, the system helps hold the lane.
Staying “between two white lines” describes lane-keeping behavior—maintaining the vehicle’s position within marked lane boundaries. This is a common capability of advanced driver assistance and autonomous driving stacks.
responsibility that the individual has to the truck
"Seems like a win-win and you haven't changed the responsibility that the individual has to the truck which is still 24 hours. You've changed what they do over that 24 hours."
Even if the vehicle drives itself, a person may still be responsible if something goes wrong. That’s why the driver might still have to watch and be ready to take over.
This refers to the human’s legal/operational responsibility even when automation handles driving tasks. Many real-world systems still require a person to supervise and be ready to intervene, which affects how autonomy is deployed.
asset to be productive 22 hours
"It's allow the driver to be productive. Allow the asset to be productive 22 hours and repeat it many times."
They’re talking about using the truck more efficiently—getting more hours of real work out of it. Automation could help the truck spend more time moving and less time waiting.
This is a logistics/economics concept: maximizing utilization of a truck as an “asset” by reducing downtime and increasing time on task. The speaker ties higher utilization to automation, suggesting fewer constraints on when the truck can operate.
OSHA
"So and as you were saying that's that's a that's yeah right well if hey for office workers don't they like being on the office worker with with a nice office isn't OSHA supposed to go in there and look at the surrounding ours for workers..."
OSHA is a U.S. agency that focuses on workplace safety. The speaker is asking whether OSHA would need to review safety concerns if truck driving becomes more automated.
OSHA is the U.S. Occupational Safety and Health Administration, which sets and enforces workplace safety rules. The speaker brings it up to question how safety oversight applies when truck driving tasks are automated and the driver’s role changes.
modern AI
"Alan you've got a link to a book in the latest newsletter. Why machines learn the [1952.1s] elegant math behind modern AI by Anil Anantaswamy highly recommended by someone you know."
Modern AI is the kind of computer “learning” used in today’s apps and systems. Here, they’re recommending a book about AI, but then they explain it’s really focused on self-driving cars.
“Modern AI” refers to current machine-learning approaches used for tasks like perception and decision-making. In this segment, it’s mentioned via a book recommendation, but the speaker then narrows the discussion to how AI math applies specifically to driverless vehicles.
ride-sharing simple economics
"why not we'll see what happens especially when it's ride-sharing simple economics right [2054.3s] I think so although you know airplanes have can you airplanes well yes"
They’re saying the reason ride-sharing makes sense is basically money and efficiency. If more people share one trip, it can cost less and use less energy than everyone traveling separately.
“Simple economics” in this context means the cost and efficiency logic behind using shared transportation instead of separate trips. The speaker suggests that ride-sharing can be more efficient (including energy efficiency) because it consolidates demand into fewer vehicle movements.
driverless vehicles
"it's not the math behind modern A to I it's really the math behind driverless vehicles"
Driverless vehicles are cars that can drive themselves. The host is saying the book is about the math that helps make that possible, not just general AI.
“Driverless vehicles” are vehicles that can operate without a human driver, relying on perception, planning, and control software. The speaker clarifies that the book’s focus is the math behind driverless vehicles, connecting AI theory to the specific challenges of autonomy in real driving.
