I thought the key point of Googles new tiny & slow self-driving car is that it is so slow, that "just stopping" is the adequate solution to all unforeseen issues. This would give the driver enough time to wake up & take over. (Or someone does it remotely). And really, from all issues that might be open, I am sure that traffic lights are a solved problem. How hard would it be to pass a law that requires all (mobile) traffic lights to send out some radio-signal to communicate with self-driving cars? Such an emergency stop signal would also be useful for human-driven cars.
