Earlier quoted context omitted.
Dude it's totally following the law. You're allowed to enter the intersection for an unprotected left even if it's not clear to turn (possibly not if the end of the intersection you're going to is full of cars). If you are in the intersection, you're allowed to clear when possible regardless of the color of your light. Most intersections with unprotected left turns let you fit at least a whole car, sometimes two in t…
While you are allowed to enter the intersection during a yellow, you are also considered legally to have been warned and would be consider liable if doing so causes an accident. This extra liability would seem like making self driving cars error on the side of stopping to be in the interests of auto makers who would be exposed to that liability.
Imagine how crazy the law would be if this were the case: - Light changes from green to yellow 1ms before your front wheels pass the stop line - Other direction traffic runs a red light and hits you from the side - You're now somehow liable because your wheels entered the intersection with zero ability to react quickly enough (no human can react in 1ms and no car can stop that fast) and the other driver that clearly blew a red is not?
That would be pants on head crazy, tbh...
