We don't need self-driving cars that can go anywhere (ie. level 5) for them to be widely useful. A car that only worked in bright sunshine on a preprogrammed set of roads would be immediately useful to me.

Semi trucks, solely on well done roads (Interstates in the US) seem more likely to happen sooner. There's an obvious strategy for "ports", dealing with exceptions, etc.

Tesla frequently talks about platooning when touting their Semi. "Self-driving" by almost blindly following a human-driven lead vehicle doesn't seem that far off. But I'm not looking forward to the day when I see a "train" of semi trucks speeding down the interstate only a foot or two apart from each other!

If the standard of self-driving becomes something akin to how airplanes fly, then weather will be a delay, bypass, or do not fly precondition to the execution of the flight plan. All this stuff about "it's right around the road" vs "it'll never happen" is all unspoken assumptions around what it means to take a "safe" "trip" "in a car" "driven" "autonomously". Safe? Compared to humans that are alert, humans with smart…

Get ready to have your mind blown because the next leap in this line of logic is to physically fix "tracks" to the road and run the cars on these "rails" - possibly on a schedule.

It's a future star-trek world we in the United States can only dream of ...

How about a gunman stopping the car. Will the car just let the passengers be robbed or executed mafia-style? (I'm rewatching The Sopranos)

I've always wondered why more attention isn't paid to this. A driver's ability to make a decision to run over a possible assailant is a huge deterrent that is not fully appreciated. To an autonomous vehicle all people will look the same and they will have to stop. I'm most curious about the self-driving trucks. If they are driving across the country through sparsely populated areas, what is to stop a group of robbers…

All those sensors on the truck will be very useful to police investigators afterwards. Sure they make off with cargo, but theft is illegal even if it isn't robbery. The police are generally pretty good (despite the real cases of bad apples). In most cases "the cops say they know who but there is no proof" (obscure Stan Rogers reference), and the truck will upload the proof they need in real time.

I think there is no reel need for driverless cars. Having technological difficulties aside we should question whether there is really a need for self-driving cars. Life is not that bad without autonomous cars. I don't hear anybody complain about in real life not having driverless cars. Basically a driverless car is same thing having a private chauffeur and I know quite a few people who don't want to use their private…

I complain about it. I've lost good friends to bad drivers. I can't figure out how to improve humans so I'll take self driving cars when they get better than humans.

That could work, for the platoon, while on the interstate.

It might not work for other vehicles on the interstate, though. If there's not room to pull in between them, then you have to pass all of them at one time. If you're a semi that wants to drive 1 or 2 MPH faster than them, that's going to be a very long, slow, pass. It will be even worse if it's in hilly country, where the semi attempting to pass may have higher speed on flat ground, but less power for climbing. That could block both lanes for a really long time. Human drivers in cars (some of whom want to drive faster than semis, and have more horsepower per ton at their disposal) will be very annoyed.

Then you get one "train" trying to pass another, and things get even worse.

Then the train gets off the interstate. They hit a traffic light. Less than all of the train makes it through the light in one cycle. Now what?

Accident rates in the US on the highway are on the order of one per million miles. And in a million miles of driving you will encounter quite a few stationary or otherwise unexpected objects in the middle of the travel lane.

Good example - deer. But human drivers hit deer all the time, and it's often unavoidable. An autonomous driver is probably more likely to miss a deer than a human, due to substantially better reflex time.

And one would think infrared vision that could be useful (except possibly when it's a magic number between 98.6 amf 104 degrees somewhere)

To me, every brown mailbox with a white reflector could be a deer coming to the road, to infrared, with a larger lens, it should be able to tell a lot better.

Nothing makes a huge group of us cringe more, than people saying it's just around the corner. The worst part is it also comes from people who should know better. >Waymo’s CEO, John Krafcik, has admitted that a self-driving car that can drive in any condition, on any road, without ever needing a human to take control—usually called a “level five” autonomous vehicle—will basically never exist.

> Waymo’s CEO, John Krafcik, has admitted that a self-driving car that can drive in any condition, on any road, without ever needing a human to take control—usually called a “level five” autonomous vehicle—will basically never exist. That's equivalent to saying AGI is impossible. It's a pretty big statement.

I'm not sure it's any bigger a statement than saying that it is possible, though...

Haha :). But no, we're talking PRT here, not regular trains.

Whoa. Misunderstanding here. I’m not talking about eliminating transportation. That is just stupid. Alternative transportation from driving include: busses, trains, bikes, walking, trolleys, bicycles, ski-lifts, airplaines, taxis, boats, rollerskates, escalators, etc. The sum of these alternatives will almost always outweigh driving in terms of benefits with a notable exception of convenience. So if you are willing t…

Until you need to carry something with you - like luggage, or a baby.

But this is where HN is blind; a non insignificant portion of America doesn't have access to a reliable automobile. So, there are already 10s of millions of Americans (and Europeans) that transport luggage and a baby just fine.

Am I the only one who's terrified of the security implications of such a system? You're talking about running (from the car's perspective) untrusted code on a fleet of cars, dynamically and in real time. Even if it's cryptographically signed or whatever, you're one or a handful of exploits away from remote attackers having the capability to crash every autonomous car, simultaneously, at least in a geographical region…

I'm talking about doing what airplanes and ATC are already doing, but in an automated way.
