This was actually a very mild honk while in a RTOL approaching a red, but after the turn the driver yelled at me to get on the sidewalk. This same driver has honked at me several time before/after - if it were not for the yelling at me and the other honks it would almost seem a 'courtesy' honk, by an unaware driver. (ingore the break squeal, it has been fixed)
