Lyft CEO: Self-Driving Cars Aren't the Future 451

Nerval's Lobster writes Google, Tesla, Mercedes and others are working hard to build the best self-driving car. But will anyone actually buy them? In a Q&A session at this year's South by Southwest, Lyft CEO Logan Green insisted the answer is "No." But does Green truly believe in this vision, or is he driven (so to speak) by other motivations? It's possible that Green's stance on self-driving cars has to do more with Uber's decision to aggressively fund research into that technology. Uber CEO Travis Kalanick announcing that self-driving cars were the future was something that greatly upset many Uber drivers, and Green may see that spasm of anger as an opportunity to differentiate Lyft in the hearts and minds of the drivers who work for his service. Whether or not Green's vision is genuine, we won't know the outcome for several more years, considering the probable timeframes before self-driving cars hit the road... if ever.

      That may be true. However, self driving cars are an entirely different matter. While they are really cool, do you really want to be in one hurling down the highway at 85MPH (I'm in Utah) and trusting that the automated systems are going to know the difference between a coyote or a tumbleweed? There are an incredible number of obstacles that a person can instantly recognize that even today, a computer can't. If a child and a dog run out into the street at the same time from opposite sides, do you trust the car to make the right decision as to which it will run over? How would you like to be legally responsible for your self driving car if it runs over a child? What about black ice? What if a person is in the road and the car has a choice of running over the person or crashing and possibly killing you. Do you trust the car to make the right decision?

      As much as I like software (and writing it), there are IMHO too many judgement calls for a computer and in many situations too many for a lot of (supposedly sane) people.

      The only way I can see self driving cars really working is to have special roads to carry them. These would be isolated from regular traffic and most of the regular road hazards. They would be in many ways analogous to a set of rail road tracks. (You don't see trains often running into problems with obstacles -- though when they do, the train usually comes out ahead.) Once you get to where you generally plan on going, you jump off and drive the rest of the way manually.

        I notice that a lot of your examples are the type of "You are already screwed."
        The point of self driving cars is that they don't take the risks humans do and don't end up in those situations.
        Also, in the examples you mentioned it is pretty common for humans drivers to panic and make the wrong or no decision, heck, I've even seen drivers let go of the steering wheel when panicking.
        So to the question whether I trust a car to make the right decision the answer is that I know that I don't trust human drivers. I

          Not only do automated cars not panic, but they can notify and coordinate with other cars on the road. With human drivers, even if you spot the obstacle up ahead, what's to prevent the asshole behind you from rear-ending you as you brake? With automated cars, the braking car can signal the cars behind it, and they can start applying the brakes before it's even humanly possible to react.

          Automated cars will surely not be perfect, but human drivers have an atrocious safety record.

            Compare the number of miles driven and/or the number of distinct trips to the number of accidents. I think you will find that humans are far from being atrocious drivers. Don't let confirmation bias cloud your thinking.

        SDCs are not perfect. They will make mistakes. But, because of faster reaction times, and 100% attention span, they will make fewer mistakes than humans. If a dog and a child run into the road at the same time, a human might make a better decision, or a computer might make a better decision, but the computer will certainly have an extra 500ms of braking time.

          More like 1500ms of braking time (it is likely the child / dog running into the road is an unexpected event so reaction times are *much* slower).
          • The problem is that in the big city with all sorts of chaos, your self-driving car is going to crawl at 5km/h to avoid *every* possible hazards. Part of a successful commute is to accept some of those risks, but a computer won't be legally allowed to permit that.

          Because there is nothing to say a human driven car can't contain collision avoidance software for such an eventuality. As some cars already do. It's not self drive car or nothing.

          It's easy to see that self driving cars will come if you look at it as a feature. Take a normal car with a self driving button that you can switch on and off at your own judgement. You don't have to use it, but slowly you start to detect situations where the self driving button comes in really handy, such as traffic jams. And then some slow city traffic. And as confidence grows you switch it on on a long highway journey.
          So you end up with all the cars having the option but some never use it, others sometime, some as much as possible.

      • The only way I can see self driving cars really working is to have special roads to carry them.

        This may well be the best way to do it, at least initially. A sort of small train wagons that could aggregate into whole train sets for part of the way and split off to different routes when appropriate. The biggest problem with public transport atm is that trains and buses are too inflexible - they don't go exactly to where people need them, and they too often aren't full to capacity - and when they are full, they are usually not big enough.

          The biggest problem with public transport is the lack of support from govt to implement it properly. If you design and zone your city around your public transport then it does indeed go everywhere you need it. The problem in the West is we planned cities around the dream of the motor car and sprawling suburbs, then when we finally realised that that design doesn't scale well, tried to tack some buses and trains in where could and ended up with a mess.

        Odds are that if the car's in a residential location where that's likely, it's going slow enough that it can either stop in time to avoid hitting both, or it's so close that neither the human nor the computer would have the choice of which to hit.

        In testing, the computer driven cars are generally able to stop so much faster than a human that, in a case where a human has to 'make' a horrible choice of what to hit, the computer driven car has already stopped short.

        Considering just the bottom line, I see automated vehicles as an inevitability, whether we like it or not. Companies will always seek more profit, and what's cheaper than having a driver you don't have to pay, works 24/7, will never complain or quit, and doesn't need benefits either. Lobbying will make this happen. They already own congress.
      • Great examples. Self-driving cars will never become a reality for a simple reason: liability. Can you really hold a person responsible for "decisions" of less than perfect software? That means the entire liability falls on the company making/using the software. Even the mighty Google couldn't afford the insurance policy for something like that.

        • Very likely the reverse.

          I'd imagine that most accidents involving automated cars will *provably* (video and telemetry info and all that) be human operator's fault (or the other driver)... suddenly humans will find their insurance go sky high, while insuring a self driving car will be dirt cheap (they'll be harder to steal too).

Or more likely they can sit inside reading, just to be present as a chaperone for the car in order to prevent their property from being part of a dramatic re-enactment of the Johnny Cab scene in Running Man...

    Either way, less work.

    I'll tell you what the future is, and the CEOs of Lyft, Uber, etc. know it as well:

    Self-driving car-sharing vehicles.

    I'm a huge fan of the new car-sharing services that have popped up in recent years. The ones where you simply pick up a car wherever you find it (your iPhone App will show you the nearest ones if you are looking), drive to where you want, and leave it there for the next person to take.

    You have a car when you need it, don't need to bother with it when you don't, you don't need to worry about fuel, inspections, washing it - nothing. And you can take the car you need for today. Good weather? Cabrio. Need to transport something? Bigger trunk. etc.

    Main disadvantage? Sometimes there's no car nearby, and of course the usual parking space hunt in the city.

    Solution: Self-driving cars. Tap a button on your smartphone, the nearest car comes and picks you up. Just exit it at destination and it'll go away by itself, either finding a parking space or going to the next person who called one. If it's an electric car, it can also go and find a charging station if it wants.

    Who needs taxis? Who needs Lyft?

    They know this, of course, and they know it's coming.

    • Hey you mentioned something that I never thought of before. How does the car sharing service pay for parking? If you use a car that's been parked for 10 days do you have to pay $300 in parking fees?

      • 1. It's a self driving car, it has 'all day' to make it to the cheap lot
        2. If it's cheaper to drive home, have it do that.
        3. If you're commuting, it's generally cheaper to pay by the month, not by the day, so the car would have an RFID or something for the lot of choice.

        Oh, you're talking about the current car-sharing services with non-self driving cars.

        The answer there is that they lease dedicated parking spaces for their vehicles. They get agreements with the parking garages and such to get 'group rat

        How does the car sharing service pay for parking?

        The ones I use have agreements with the city that they can park on any public parking spot for free, even if you need to pay with your private car there. I don't know if they pay a yearly flat sum to the city or if the city sees it as a quid-pro-quo deal because of the reduced space usage and traffic.

    • Main disadvantage? Sometimes there's no car nearby, and of course the usual parking space hunt in the city.

      You think THAT is the main disadvantage?

        That's because you consider it an additional room in your house. I know people who do that, but I never did even when I had a car there was almost nothing in it. Note that I didn't say self-driving car-sharing will replace all private car ownership, that would be stupid. But it will replace taxis and ride-sharing.

        And those cars don't get stolen?

        They're equipped with GPS, you sign up with your drivers license to these services and unlock the car with an RFID card. So basically they know who you are and that it was you who took the car.

      - Kids can use it (for instance when you don't want to have to pick up your kids at their soccer training)

      This already exists in places like Hong Kong and Singapore, and is starting to take hold elsewhere. The exodus to the suburbs in the 60's is slowly being reversed as people appreciate the convenience of living close to amenities. Inner cities are being gentrified, more people are choosing apartment living, because convenience beats everything. Being within walking distance to everything means never having to worry about a car, self-driven or not.

      I'm really sorry to have to be so direct but that is the dumbest argument I've ever heard.

      Driving is not a matter of intelligence. It's a matter of reaction. Sure, intelligence and experience help you anticipate when other drivers are being idiots, but there is very little involved in driving that can not be compensated by reaction time and adhering to proper distances.

      The biggest hurdle to take is to correctly measure the surroundings. If you did that via image recognition, then yes, AI would be important. But there is laser, radar, GPS and so many other sensors involved that do nothing more than note distances to targets, location on road etc.

      Autonomous driving certainly isn't trivial, but the other thing you have to keep in mind is that your oh so intelligent human drivers are actually driving like morons a lot of the time.

      Please stop putting the bar for autonomous driving so high the systems have to practically be perfect the be viable. The moment they are twice as good as a human should be the moment we start switching. And we're not far from that.

      Remember how badly the average driver actually drives. And then remember that half of them drive worse than that.

      Add on top of that networked driving, where cars coordinate over several hundred meters and you'll see so much potential gain even from non-perfect systems it's staggering.

      • The moment something in reality changes, the map is wrong.

        The moment there's radio interference, the GPS doesn't work.

        The moment one of 10^20 things you know about but a machine wouldn't changes, you'd know that something was wrong but a machine wouldn't. Is it really that hard to see that having machine driving before machine intelligence is idiotic?

      • There's a lot of filtering to hide just how inaccurate GPSes are. That doesn't matter when a human is looking at a screen and ignoring it when it's obviously wrong. But it makes a huge difference when an idiotic machine is driving.

          Seeing as it doesn't use GPS to drive the car, just to navigate, your argument applies precisely as much to self-driving cars as human-driven cars.

    Self driving cars operated by the owner are a different situation from that of self driving taxis. The owner and rider interests diverge when those are different people. A self driving taxi has to protect itself from theft & abuse and protect its owner from lawsuits. That mean the person riding in the taxi won't be allowed to arbitrarily stop it, assume manual control, or exit in locations considered by the taxi owner to be unsafe. Putting my car in self driving mode with my average speed 10 mph in gridlock sounds attractive. Getting into a little vehicle capable of traveling to arbitrary locations and trusting it like I would a train takes the early adopter impulse right out of me. Maybe self driving buses would make the transition better.

Maybe it won't go offroad or pull up the driveway for me, but street address to street address it should be "close enough" unless I got 30kg of luggage. Otherwise I can complain and maybe they can do a remote drive-by-wire or get half off / refund.
