Last week I made a right turn out of a shopping plaza and was immediately confronted by a 17-ish cyclist, going the wrong way (IOW, against traffic, headed directly toward me), with a huge slurpee in the hand nominally on his handlebars while talking on the phone with the other hand.
Oh, and he had a girl hanging on his back while all this was going on.
Because of traffic flow, I had to brake completely and let this wreck of human debris pass by (going in the wrong direction, mind you) until continuing. There was a small caravan of vehicles behind me who had to stop as well.
I ride the wrong way on sidewalks on rare occasion. I am also fully aware that cars pulling out have the right of way and if we collide it is my fault.
I ride accordingly.
If a car is pulling out, I will either turn left at the car and go around the back of them, or I will come to a complete stop and let them out of the lot.
