Knock on wood!!! I am !! All these capricious accidents really have no common denominator except fuc*ked up drivers of cars or target type bike riders. I live in DC which has the second worst traffic congestion compared to LA, except for time at lights and accidents*. (* = what's that? Well. some BS statistic meant to mitigate that number... Sounds like we're No. 1 to me).
I am very aggressive, I try to radiate it; For years I'd get up thinking today 'let's be mellow and just enjoy the ride'. Within two intersections some self centered SUV parasite is cutting me off, whatever...
After about 1/2 mile I'm back in defense mode, gotta be. Then Offense Mode, cut me off, squeeze me out; then off with your right mirror. You're commercial; taxi, truck, bus (for hire) reaping profit from my over-taxed infrastructure, off with the left mirror ( hard to drive auto without a left mirror!) Open your door without looking over shoulder? Wanna give me the Door Prize? Next time you'll think about it after I spring your door AND it slams right back on you.
I'm 53 been riding for 45 yrs. most always on busy roads, seldom wear helmet, never spandex and knocking on wood.
I think if we acted like the selfish a*sholes most these drivers are we'd command a lot more respect.
