Actually according to a bicycle magazine article I just read only 18% of all bike accidents involve cars. 70% are solo and 50 are of the falling over variety. From most recent bicycling magazine issue.
Is that specifically for "serious"[1] accidents though? My point was more that there are plenty of accidents which you can brush yourself off and walk away from, that would lead to almost certain major damage to an unprotected phone on your handlebars.
Would be interested if you have the article ref though, if it is serious injury, I'd have expected cars to play a much bigger part.
[1] Not sure exactly how you'd define this, maybe anything requiring a hospital/doctor visit.
My guess is it is for anything serious enough to seek medical attention, be it a hospital, ambulance or police and release under own recognizance, and maybe accidents at ski areas during summer with patrol. It definitely includes many non-crash emergency room visits.
