Yeah. People have died from standstill crashes just by falling off their bicycles. You don't have to crush ribs to kill someone. You just have to hit your head on anything harder than a pillow at the wrong angle.
I don't believe it. Who has died from a 5 mph impact? Who has died from a standstill crash?
And even if it were true... Jeez, you can find one person who has died from nearly any goddamn thing. Doesn't mean that the act itself is inherently dangerous.
Yes. You're putting children at risk due to an unwillingness to wait thirty more seconds before passing safely. This is what people here scream bloody murder over whenever cars do it to cyclists.
No, you're not putting children at risk by riding away from the bus (in the street parking area) at 5 mph.
