Re: The next step
It would also be useful if the car would offer a tiny little toot for drivers in front of it who have spent too long without noticing that the light is green.
OTOH, you can see what's going on with the driver in front of you. Are they clearly distracted and not likely to be moving any time soon? Or did they just drop something and they're picking it up or whatever and they're clearly about to move -- in which case even the lightest, most polite honking will accomplish nothing but ticking them off. Can current AI technology be programmed to observe and read this correctly today?
