I've really got to appreciate how the crash started when the chain just "sorta flew loose." It sounds absolutely terrifying.
Naaah. See bicycle mishaps involve your mass, ~20lbs of chrome-moly and whatever immovable objects tend to be around, assuming you're clear of traffic. Those can go bad (and they have! Believe me, they have) but the physics are still in the "sports" regime. You get one of these involved and suddenly you're sliding across 4 lanes of the 405 because some fuck in livery figured NOW was a great time to exit the carpool lane, despite the double yellow, and you're hoping that everybody stops 'cuz you're sideways and there's 430lb of Italian exotic lying wounded on the road. Refocuses your perspective on bicycle accidents I tell you what.
