If the motorcycles weren't there wrecks would not be as readily attended to or noted (several of them have cameras I have noted). The incident with Phinney was very unfortunate but hey, weren't police and farmers fighting with tear fas the other day and the race was halted when the canisters were hurled into the race course?
Aren't there also support cars in that mix?
Tear gas! Not your average problem in the TdF!
