I think the answers to those are: > Does this ball running into the road, means a child might be running behind it? There's no ball. There's merely a non-car object on the road, which means you smoothly stop and alert the driver. > Does the pedestrian on the sidewalk with headphones and looking at the other side, not seeing my vehicle and the red light, is going to cross anyway? If an object intrudes on the road, and could collide with the car, brake as per above. > Since there is crashed truck on the road ahead, does this police officer making me signs to temporarily cross to the other side of the road, wants me to drive ahead ? Do I see its Ok anyway, because his colleague on the other side is holding the traffic coming this way? There's an obstruction on the road. Brake, alert the driver, have them figure it out. > Can I go off road for 2 minutes because the hole in front of me is too big and the off road track looks good? No. Self-driving cars only automatically drive on a proper road. > The discussion of how sensors are better than humans, and the systems don't get tired compared to humans misses all these. My view is that this kind of thing just tends to over-complicate the issue. The initial goal shouldn't be an AI version of a human driver, a system that recognizes and knows about balls, children and police officers. It should be the car equivalent of an elevator -- a dumb machine with safeties that automatically stops if anything isn't right and waits for a human to figure it out. An elevator doesn't know what's standing in between the doors. Something is, therefore the door doesn't close until it goes away.

> There's an obstruction on the road. Brake, alert the driver, have them figure it out. That is the whole crux of the problem. There is no driver, it was supposed to be self driving. Like many of the "self-driving taxis" in San Francisco whose passengers might not even have a driving license. > No. Self-driving cars only automatically drive on a proper road. Not good enough. All those human driven cars handled the situation is seconds. Now all your "self-driving" cars are causing a huge traffic jam. In the meanwhile the police has just open a second lane for the human driven cars to overtake the AI ones....

For such a problem, call the home base, have a remote operator figure it out. > Not good enough. All those human driven cars handled the situation is seconds.

I don't imagine we're going to have fully autonomous cars any time soon. There will need to be a human in the loop somewhere. On a longer term, I can see a police officer having some sort of device or signal, hopefully authenticated, to give the car an understandable command.

      Self-driving is a spectrum, not an absolute.

      To a very substantial level. Everything needs maintenance and monitoring. My web server runs on its own 99.9% of the time, but I'm still needed

An elevator doesn't know what's standing in between the doors. Something is, therefore the door doesn't close until it goes away. Here is your issue: you are describing an automated train. A remote operator can pilot it if anything odd is happening. This model doesn't scale well for individual cars, especially on open roads where everything can happen. For this you need a driver inside the car. A self-driving car requiring a driver is not that "self-driving".

  > A self-driving car requiring a driver is not that "self-driving". That seems more like a philosophical issue than engineering at that point. All technology requires some amount of monitoring, maintenance and troubleshooting. You don't need to solve every possible weird event happening for automation to be useful. The main two use cases as I understand are: * A qualified driver sits in the car, just doesn't want to drive. They can be asked to assume control any time it's needed. * The vehicle forms part of some sort of large fleet, and can be managed centrally. You'll always want some amount of central control for a fleet. What if the car breaks down? What if somebody else crashes into it? What if somebody tries to steal it?
