Why Self-Driving Cars Should Never Be Fully Autonomous (roboticstrends.com)

An anonymous reader writes: David Mindell, an MIT professor, says self-driving cars should never be fully autonomous. "There's an idea that progress in robotics leads to full autonomy. That may be a valuable idea to guide research but when automated and autonomous systems get into the real world, that's not the direction they head. We need to rethink the notion of progress, not as progress toward full autonomy, but as progress toward trusted, transparent, reliable, safe autonomy that is fully interactive: The car does what I want it to do, and only when I want it to do it." Mindell writes, "Google's utopian autonomy is a more brittle, less functional solution than a rich, human-centered automation."

      It's called a "rental car," and it's not a new concept.

      And like rental cars today, you'll have the exact same responsibilities as you do with your own car. If car owners are responsible for making sure their own cars operate safely, you'll be responsible for making certain the rental does.

      Perhaps what you really want is a "taxi," which as a trained, professional driver, who knowingly accepts that responsibility (and control) for himself. Or maybe an Uber driver who may or may not know his ass from the glove compartment, but who is still responsible.

      This is purely a cost-benefit analysis, and what's true for you will not be true for others.

      If you purchase the car new for $30,000 (smart people don't, but we're talking the typical car buyer here), use it for 5 years, and sell it for $15,000, it depreciates an average of $3000/yr.

      The average car in the U.S. is driven 12,000 miles/yr. Gas for 12,000 miles/yr, at 25 MPG and $3/gal, works out to $1440/yr

      Maintenance and insurance is around $2500/yr (mine and maybe yours is a lot less, but we're talking the typical, median driver here with an accident or two on his record).

      Total cost of ownership is then $6940yr, or $0.578/mi, which is almost exactly the IRS reimbursement figure of $0.575/mi so we're on pretty solid footing here. If you use the car on 300 days out of the year, that's $23.13/day.

      Can you do everything you usually do in a typical day of driving the car for $23.13? If you live in a city with good public transportation, the answer is probably yes (ignoring the cost of time you have to wait for said public transportation). If you have to rely on taxis, the answer is probably no. And if you live outside the city the answer is almost certainly no.

      There's also the tragedy of the commons to worry about. I just got back from taking my dog for a walk at the beach, and there's wet sand all over the back seat. Do you really want to get the autonomous car right after I've used it to ferry my dog around? In a taxi, the driver's presence discourages you from abusing the shared asset. You won't get that with an autonomous car unless the car service puts cameras inside them that are always recording. Which would could as a huge negative for a lot of people in the buy vs rent a car argument.

      So I'm going to try. Putting aside fatalities, as the Google cars have not been involved in any, there were approx 5.5m traffic accidents in the US in 2010. Taking your number of 1b trips per day, we get a figure of ~66k miles per accident. According to Google they have been involved in 11 accidents over 1.7 million miles which is ~154k miles/accident. Now this is a combination of fully automatic and driver assisted miles, so the comparison isn't exact, but it's pretty safe to assume the computer is at least as good as your average driver. And maybe twice as good.

      That may be evidence of it driving badly. Or it may be evidence of it driving well, because it was responding to a potential danger that the human drivers didn't see or didn't care about. Remember - if we're saying we want the computers to drive better than humans we have to accept that they will at times drive differently.

      Rear ended from behind while sitting in the HOV lane with stopped traffic (50+ mph- evidence the human didn't even brake until he was 20' behind doing over 50mph).

      NONE of these accidents would have happened had a google car been driving.

      If nothing else- I'd like cars to start slowing down automatically when they detect a collision is about to occur. And prevent a driver from flooring it into another car ahead or behind them when both are stopped.

    I don't think we'll have self-driving cars right away. Instead, we'll have cars with "Enhanced Cruise Control." You get into a lane on a highway, hit Enhanced Cruise Control, and your car will stay in that lane (turning left or right as needed) keeping to the speed you set but slowing down if needed (e.g. if the car in front of you brakes). For long car trips, this would mean that a bulk of your trip would be automated. You'd still need a driver there to take control once you wanted to leave the highway and you might not be able to use this during bad weather (just like you wouldn't put cruise control on during a snowstorm), but it would be one step towards autonomous cars.

    As the software gets more refined and the edge cases are dealt with better, the car will be able to handle more driving situations. For example, "automatically stop at red lights" or "keep going straight unless the driver indicates otherwise." Eventually, cars driving themselves will be the norm and human drivers will be the exception.

    Because people are irrational. We fear exotic deaths more than we do mundane deaths. Travel by airliner is much safer than travel by car, yet every time there's a plane crash we have a huge investigation for the purpose of figuring out what went wrong so we can prevent it from happening again. But tens of thousands of people die in car accidents, and all they get is a brief police report stating it was an accident without really delving into the cause. Why? Because death by airplane crash is more exotic than death by car crash. The same thing plagues nuclear power. Death by radiation is exotic, death by falling or getting lung cancer from soot inhalation is not. So we scrutinize and heavily regulate everything to do with nuclear power when it's already the safest power source we've ever invented in deaths per MWh of power generated, while turning a blind eye to deaths by coal (pollution), wind, and solar (primarily falls during maintenance - their diffuse nature means there's a lot more maintenance to do).

    You double down on this if the accident was in your control vs out of your control. If you could've done something to prevent the accident (was driving a car) but failed to so, you say "Oopsie, I won't make that mistake again. No give me my keys back." If someone else could've done something to prevent the accident (driving a bus or piloting a plane) but failed to do so, you sue the bastard for everything he's got and try to get him banned so he never drives/flies again.

They might look around once in a while but they're not going to maintain the kind of focus on the road that would give them any kind of real situational awareness. It's just not going to happen. There's no reason to pay attention when your car is driving itself. And don't kid yourself. People may say "Yeah, I'd stay focused on the road." But they're full of crap. Anyone behind the wheel is not going to pay anywhere near as much attention to the road when the car is driving itself as they would when they're driving the car. If you have to pay attention to the road, why have the car drive itself in the first place?

    Suddenly, the car runs into a problem that it can't deal with so it hands over control to the driver. But this "driver" has no idea what's really going on. Hell, it will probably take a fair number of seconds for the person to realize that the car has handed over to them in the first place. Reaction time will be slowed substantially by the fact that they have been lulled into a false sense of security. They are entirely unprepared to take over at that moment. Suddenly being forced to change focus is difficult and time consuming. And a lot can happen in the many seconds it takes for the average person to realize what's going on well enough to do something about it.

    But here's the thing. The only reason the car would hand over control is that it is in a situation where it doesn't know what to do and that usually means there's something significantly wrong RIGHT NOW! Given that, do you really think it's a good idea for the computer to just say "screw it, I'm out" and suddenly dump control over to a passenger who has no idea what's going on around him?

    No, the idea that an autonomous car would have an option to hand over control to a passenger in the car is ludicrous on it's face. There's no way in hell anyone would design a car to do that (for the consumer audience) once they spent a few minutes understanding the problem. For research cars that get used in controlled environments? Sure. But the first average consumer caught napping when their car handed off control would sue the hell out of the manufacturer if they survived the crash. Or the family of the person would sue if they didn't. Either way, that kind of liability is just not something a manufacturer would ever consider taking on when they're building for the public.
