The possible improvements would truly need mind blowing. I can't even think of a reason why those cars would have to stop asking the way if everything goes right. There would be no more need for traffic lights or stop signs to coordinate traffic between cars. You would still need them for pedestrians. However, if the traffic lights are integrated I the same system as the cars then the cars can just adjust their speed to not have to stop at the light. Their gain in fuel efficiency would be huge! As long as nobody jaywalks or we have cross walks without traffic lights or bicycles..

It would also be great when a traffic light turned green that all cars started moving at exactly the same time, as opposed to the delay where every car waits for the car in front of them to start moving with human drivers.

Fuck I hate it when people do that i.e. 99.99% of the time. Just go as soon as the person in front of you starts going and build your gap by accelerating slightly slower than the person in front of you _after_ you are on the other side of the traffic light.

Without having a gap before you start, how do you plan on stopping in time if the car in front stops suddenly? Which they might do if they see someone running the red light, or a pedestrian thinking there's just enough time to run across.

The needed gap is proportional to your speed. Starting speed from a stop is quite low so the gap needed is low. As you gain speed you expand the gap.

You can't all accelerate at the same rates and expect the distance between the cars to increase. The slow trundle off the starting line is needed to establish following distance.

That is why I said accelerate _slower_ than the person in front of you to build a gap. (Once you are on the other side of the traffic light)

When the light goes green everyone should go at the exact same time and acceleration. Because you just started moving your speed is very low, so you don't need a large following distance.

You are clearly one of the millions of people that doesn't understand this.

If competing commercial systems are allowed, they might try to game the various systems as a matter of competition. To fix it, the regulation ends up being a form of government mandated mass transit.

Definitely an interesting scenario (not sure why you were downvoted). New enabling technologies may promise the potential for utopia, but human nature persists. If the standards for the technology can't come from competitors cooperating, we're left with regulation. Forgive me for repeating your point, but it seemed lost on some, perhaps unintentionally.

Where we will we get the new rules for a new road?
