Several times, mostly in places where separate bicycle paths cross with roads. Last one - the car had stopped, as it should have, to let me pass, then stepped on the throttle and swerved towards me, after I had slowly passed it's front - I thought he was deliberately trying to kill me. Turns out he was distracted by kids in the back seat and didn't even see me - he had stopped to calm the kids down - sun was into his front window so I didn't see his face (or head).
