I'm sorry, I just don't see how a mirror would have saved the o.p. unless he spent so much time monitoring it that.... ... BAM! Front end taco'ed, over the bars and whatever can result from that. A camera? Two camera's? Really? We are supposed to invest as much or more than we spent on the bicycle in video recording devices? Do you think a driver can see your GoPro on the back of your helmet if he didn't see YOU? If a bicycle is traveling at speed and is rear ended by a car that is traveling enough faster to do the kind of damage inflicted in the above accident the bicycle operator should have heard it coming up behind him. Unless he is HOH and that wasn't said in the o.p. You don't have eyes in the back of your head, and mirrors are NOT, eyes in the back of your head. You have EARS, however, that operate in 360 degrees. Finally... ... the o.p. said "I was tooling along in the right lane... ..." I only ride "in" lanes when I have a car wrapped around me. If not, I ride out of the traffic path as far to the right as possible. Of course it is still possible that a driver that way out could come after me because he is bent that way but it is unlikely, in that event, that any responding LEO would be as smarmy about it.
