What he said. Legislation will be the biggest problem to autonomous cars. If the driver is still responsible for the vehicle, even if the vehicle does have an accident, then as Wills2 said, it won't be possible to go to the pub get rat arsed and have the car take you home, or work whilst she commuting, etc. If that happens to be the case, what is the point of them, you haven't freed the driver of responsibility, therefore they have to be paying attention and prepared to react, in which case they may as well be driving.
This is the big issue. We don't have accidents any more, we have collisions.

Someone is responsible and it sure as hell won't be the manufacturer, so it'll be the driver.

Which means the driver will have to be qualified, medically fit, sober and paying attention before being legally allowed to be driven by their car.

I just can't see the law letting it be any other way.

I can see it working on a busy motorway if all cars are driverless and communicate with each. If the ultimate aim is to get x vehicles quickly through a difficult junction then I think that a group mind-set of cooperation and the 'greater good' mentality is the best one. It avoids the human frailties of selfishness and a need to singularly dominate others (which are all to easy to witness on the roads) which normally knackers things for the group.

It also avoids the delayed reactions of humans. If a car in lane 3 brakes gently, the car behind has to wait to see the brake lights, move foot and apply the brake, and as such needs to brake slightly harder to maintain a safe gap. Multiply this by 30 cars and at best you get the accelerate / brake concertina effect, at worse a motorway shunt. If all the minds are linked then as the lead car decides if needs to brake, all 30 cars following could run in a train formation and brake by the same amount at the same time. I actually think that the computing prowess easily exists to get many cars from a to b very quickly if all linked.

The issue will be mixing autonomous and human drivers. That'll be hell of a thing to manage. And older cars will never be able to be retro fitted to be autonomous.

I can see a day where our motorways have autonomous lanes you can only join if you give over control. And these lanes will be faster and more efficient ways of getting from a to b. That is what will encourage the switch.

But have hope that it could be a win-win! I predict it will get to the point where motorways are autonomous only and the commute will be a chance to work or sleep, which is great, because m25 commuting sucks. And my weekend caterham will be relagated by law to only ever use some sort of forgotten, empty, 'slow' B road network. And I'll be sharing these empty roads with other oddball drivers using their weird internal combustion engines, choosing to change gears themselves, having to make all of their own decisions, getting from a to b much slower and more expensively than all those clever clogs iCars. Potentially, lovely!

It was pointed out to me that once they arrive a child could potentially use them much as anyone else. I like the idea of the 11 year old boy and his/her mates going out for cruise in the pod.

Bit of a false premise in the OP isn't it? I spend a bit more time than I should on the PH forums and I don't remember anyone saying that the demise of the good old human-driven car is imminent, or that they'll be banned soon. With the pace at which the technology is advancing I'd be amazed if there isn't a fully fledged self driving car that's orders of magnitude safer than human driven vehicles within the decade, but I'd be surprised if human-controlled cars are actually banned within my lifetime.

And the 'driver' will be less prepared to react suddenly because he won't be concentrating at the same level as if he was actually in control of the vehicle.
And then you'll get done for careless driving. hehe
Be interested to know waht would happen if the system breaks the speed limit or enters a bus lane. Who would be liable?
The human, would be my guess, that's why this autonomous utopia people keep on talking about will not happen, pissed up in the car having been picked up from the pub or working away on your laptop or watching TV.

My arse!

That's actually a very point that I hadn't even thought of. This is going towards driving pods, rather than anything actually car shaped. A bit science fiction but I'm not sure why the cars would need to be car shaped any more, no need for a steering wheel or pedals and electric cars are already changing the basic shape.

The school run would be quite different and I guess the self driving cars wouldn't park like moronic muppets either so that would be a vast improvement.

The next question, would you actually own the car? I can't see why you'd bother, you'd just pay a monthly fee to give you a monthly milage allowance and book the car when you need it, basically a personal taxi.

Ye gods, have you seen the cars some people buy? (Renault Modus, Citroen Picasso, Honda Jazz et al) There are many people out there who buy a car purely to get from A to B with as little input from them as possible. These are the people who will drive this.

In fairness a car powered by a ZX Spectrum would do a better job at parking than most school run parents

There are many big challenges for self-driving cars, but Google have overcome arguably the biggest hurdle by demonstrating it is technically possible, and further they are actually using self-driving cars on public roads. https://www.google.com/selfdrivingcar/

There seems to be a lot of goodwill from governments. The Manx government are proposing the Isle of Man becomes a testbed for self-driving cars. The Dutch have also trialled self-driving cars and busses. And in the UK they are going to trial self-driving lorries on the M6 toll.

Self-driving vehicles are 'happening' today. Nobody knows when they will become widespread on our roads, but that may occur within the EU first because of Brussels' ability to push through the necessary legal changes amongst its member states.

I read an article a couple of months ago about a test in the US: the self driving car had to join a freeway from a slip road, cross 4 lanes of traffic to exit from another slip road on the other side a few hundred metres further on.

It couldn't do it because all the cameras, sensors etc were picking up enough traffic for it to decide it wasn't safe. A human would just have stuck the indicator on and gone for it.

Perfect example of the difficulty of having normal and self driving cars that can't communicate with each other on the roads, and one reason why it is years away, if it ever happens at all.
Bit of a loaded question for the automated car - presumably if given control for the full route, rather than just that small part, it would have chosen a route that allowed it to safely get to the destination. You seem to be arguing that the computer considering a manoeuvre too dangerous to attempt is worse than a human just having a go anyway!

We don't even have driverless automated trains, which technically should be child's play. True driverless cars are a long long way off IMO.

It's interesting 'cos of the few rail incidents I read of, human error always seems to play a part.

Would a driverless train do a SPAD, or disconnect/disregard on board safety warnings?

I think that's down to the unions as much as anything else, plus the huge infrastructure changes required.

Car drivers don't have unions. And the cars work on existing roads.

I don't know about mass adoption but they'll be on the roads sooner than you think.

Which wont happen because you will have to be in charge if things go wrong which makes them pointless.

Apart from the improved safety, increased productivity and lower costs obviously, not to mention the new jobs and industries they will create.

Do you think that maybe Google, the car makers, governments and insurance companies might have had a chat about this at some point? Or are they just winging it, investing billions in a tech that is pointless because PH doesn't understand how it will work in practice?

In the short term (as in the next twenty years) yes, but if we can get to the point where we can get statistically significant data to show that they're safer than human drivers, that will change.

They will never be perfect but they have the potential to be vastly safer than the average human driver. The difficulties that need to be overcome are political and sociological, not technological. There is a huge political motivation for adopting them - they can massively increase effective road capacity at zero cost to the state; the question is how long it will take for the public to accept them.
