Or let's see if it could handle the commute I had this morning:
There was a power outage. Seems to have affected at least two blocks, including the traffic lights. I was trying to make a left turn, onto Main Street.
For those whose traffic laws may be different, in this jurisdiction, a downed traffic signal is treated as an all-way stop sign. Or at least, it's supposed to be.
Traffic coming from the left refused to stop. They just blew right through it, most didn't even slow down. Traffic from the right stopped occasionally (they had passed through other downed lights to get there, so I guess they had a few seconds to think), but that didn't help me. I eventually had to turn around and find a different route, specifically one that would not hit any traffic lights.
I wonder if automated cars would have done better. Would they have stopped, as they were supposed to? Would they recognize it as a dangerous situation, stop and hand control back to the driver? Would they just plow right through it like all the dumb humans? The first is obviously correct behavior, the second would be tolerable, and the third would be merely no better than humans were doing.
What if my car was automated? Would it have stopped? I sure hope so. Would it have realized that humans are morons and that it would never be able to make that turn? Would it plan a backup route that avoided all traffic lights, or would it continue to be surprised every time humans failed to remember an obscure driving law?
What if a policeman had been directing traffic? Do Google's cars know how to obey hand signals? People can usually figure them out even if they don't remember them, since they're fairly intuitive to us, but that has no bearing on whether it makes sense to a machine.
