In basically every example you gave, you still have to stop until people move though. The result is the same, despite everything else. The only one that's a bit iffy is if you're being carjacked, is a bit of an exception. Legitimacy isn't really the problem, it's the circumstance of a human being in front of your car that prevents you from moving forward, and beyond getting out of your car and talking to them, or just waiting, you don't have much of a choice in what options you have. I agree with the intent of your point, but what's the alternative? You can't just keep driving if someone is standing in the middle of the road.

Those were two examples, but they're not exhaustive. Traffic direction can (and often does) happen without someone blocking the vehicle. In the case of an illegitimate request, a human driver might question the request and take a different action instead. Are you being directed to run a red light? If you judge that someone is maliciously asking you to do so, you probably will choose to remain still instead. Are you being directed to stop? If you judge that someone is maliciously asking you to do so, you may choose to turn around, reverse, turn into a parking lot or otherwise remove your vehicle from the situation. You don't have to run people over to refuse a command to stop. And if you were completely blocked from moving, you'd probably call the police. My point is that "always follow hand signals" is trivially problematic. I would expect that if self-driving cars followed any hand signal they saw, you'd see kids doing it for the lulz on the sidewalk in front of their school. ..."traffic jam challenge". After all, someone is less likely to act maliciously towards a human than they are a machine.

  Okay, so your point was more about the specific directions being given, than the presence of a person in the road. Overall I agree.

One reason carjacking is rare is because people don't foolishly stop for obvious carjackings. If an autonomous car has trouble telling the difference between a carjacker and a construction worker, then it will be much more likely to get carjacked.
