Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

What happens when you push that button? Aside from the obvious.

Just that, engine cuts off. Brakes and electrics still work... As ed said driver needs to get out and reset switch before being able to start up again.

Can be immensly amusing, although obviously I've never done it...

^ oh and jumping on the curb is always a silly idea, usually when someone pulls in to block route it means there's room on the right...
