Just for being in the car? Presumably they would be questioned and released.

"Probable cause" of having committed a crime is typically the principle I believe.
> Involuntary failure to stop? Are there any laws about driverless vehicles and who is responsible for problems?
I don't know and can't imagine what involuntary failure to stop might be. I'm sure they could fit an existing law to the situation if they suspected the passenger was instructing the car to not stop.
