I agree, legal or not, I very much rely on other drivers "signals" when driving. Over the years you learn to predict what the driver in front of you would do in a normal situation and adjust your driving in advance. I'm still able to break on emergency but when you can clearly see way ahead of the car in front there is no obstacle and yet they still brake it's extremely risky and frustrating. Young drivers here usually mark the car some way to warn you to be super aware of their unexpected behavior, I'd expect self driving cars would to the same.

It means that you would have been surprised if the jogger was making a jump to her left (avoiding hole in her path for example), forcing any driver to hit the brake.

[ajmurmann]

Of course you are correct. However, we don't need to make those incidents more frequent than then already are.

I wish there were some external visual cue like a light or something to indicate a car is using autopilot. That way you could give them a wider buffer.

Maybe a pulsing red light, moving back and forth horizontally.

when you park it

"by your command"

Instead of relying on other drivers' signals, you could instead use them as extra warning, and instead of driving so close to them you're putting yourself and them and potentially others in danger if they brake when you didn't expect, you could back off to a safe distance.

Well, not sure where you read I drive close to anyone. What I'm trying to say is that erratic drivers are dangerous because you learn to predict what a normal driver would do in a typical situation (e.g. jogger too close to the lane => slow down to a safe speed and navigate towards the center).

If a self driving car doesn't reproduce the most common driving style the other drivers should be extra careful around it, some kind of mark on the outside could help.
