RLJ (Red Light Jumping). (The definitive bikeradar thread)

tim, she was a foot out from the left hand kerb, walking along like a dozy cunt and she had never observed shit, as i had mentioned previously i was in the left hand lane as i had a left turn coming up

it was time to give her a fright, it was a light tap on the shoulder, but probably enough to scare the bejebus out of her

i am sure she will look around in future

I tend to go with "Please don't walk in the road, madam." or whatever the infringement is. Or even an "Oooo, careful!" when they step out as you fizz past.

Just the fact that someone she didn't know was even there had spoken to her would have scared her. And you remain polite, so they can't (shouldn't) get the arse. Nobody hurt/upset and point still made.
