I ride a bicycle in traffic all the time so I think about the possibility of something like this happening to me as in being on the receiving end. Neither the roads nor the cars are designed with safety as a priority. I use an eyeglasses mounted rear view mirror and I ride a hybrid crossbar so that I can have my head up. That way I see all the cars both in front and in back of me and anticipate the dumbass things they might be about to do. But in spite of my caution if I did get hit the driver would get off scot free. Especially if it went to a jury trial. The jurors are all going to be drivers and drivers hate bicyclists. It’s the way of the world.
