Oh, didn't know it was something we could report. Should it be reported as "harrassing" then ?
Depends on the driver. You can have a polite chat with him, ask him if he needs something or offer him a tour around the city.
Ask him if he needs to get to a destination. Even if he asks you to give him your vehicle, you will offer to drop him to another vehicle?
If he just storms in the vehicle, starts provoking you, of course you'll report him.
As I said, depends on the driver.
