Had one idling silently next to me, genuinely thought their car just shut off on them until they took off.

Even if it just played, like, the wheels on the bus, that'd be better than silence until you hear gravel crunch under its tires.

Can’t tell you myself. Haven’t studied those laws really.

I rode in one actually, one of the lyft drivers here I took once was driving one. Really quiet thing! Never seen one traveling or that I’ve noticed. Maybe because they’re so quiet, I didn’t know. I watched the lyft driver leave because we were talking about it surging and if you listen very carefully you may hear a little of something, but honestly not really! I think I felt an object in front of me, that’s how I figured out that he was here. He was like my car doesn’t make noise, how did you know?

That’s my only experience, and I live in California.
