This is real simple. Everyone rides their own ride. How much judgement, common sense, and skill YOU bring to the ride is YOUR issue. Not the issue of another rider not affecting you, some car you are fixating on, or a camera taking your picture that distracts you. YOU are distracted. The camera is incapable of distracting you.
Own it. Good or bad.
Sucks the dude is hurt, but he probably lacks skill, training, and judgement necessary to ride safely, as so many sadly do. This is evidenced not by snobbery, but by what I see other riders doing when I am driving and riding 100 miles round trip to work every day.
Tail of the Dragon at Deal's Gap... Avoid it now, do a trackday.
Do not do business with Myrtle West Cycle... Not a reputable vendor by a long shot.
