The bike lanes that I routinely encounter are all being repainted with about 50' of the final 100' to the corner dashed, not solid. This makes (should make) it clear, to bikes and cars alike, that somehow, a right turning car has got to cross that bike lane. If its the bike lane that crosses over, same thing, at the crossover point, the bike lane (not the vehicle lane) will be dashed, for about 25', indicating that vehicles will be proceeding through the crossover portion of the bike lane.

I always assume that a car that beats me to a corner could turn right. Even if they stop first as they should, in a right turn on red environment, the reality is they could turn right. They may even have seen you. They may assume that since they have beaten you to the corner they have the ROW. They may simply not care about it. In suburban and rural environments I usually stop a car length short of a right turn situation if I am not turning right. This says to right turners, "go ahead, make my day". If no takers, I move up. Sometimes a right turner is behind a straight through and prevented from turning. Given the near total lack of turn signal usage in this town you never know what is what.

I do not "make eye contact" or solicit any other kind of acknowledgement from a road user. First it is unreliable and second my eyesight does not allow it. When the light is green I am off with the straight through car. Do not dawdle so that you can be cut down by the car behind him! If you are heavily loaded or just slow, let both cars lead through the corner so you know what they are up to.

When I learned to drive, my (excellent) driving instructor spent more time on stopping the car, quickly, accurately and instinctively, than on any other aspect of vehicle operation. In a lot of the vehicle interactions I witness, the abrogated vehicle wastes valuable milliseconds being surprised, insulted, angry, or all of the above. A collision is the result. If you prevented a crash with your Airzound or other warning device you violated a cardinal rule of my driving instructor. In well over 40 years of driving I've never used a horn in anger, ever. And I don't have horns or bells on any of my bikes. I've been riding those in traffic for much longer than I have been a driver. FWIW.
