There are soooo many instances of negligent drivers killing cyclists with basically no follow-up from the police. Police all over the US seem to consider cyclists as second-class road users, and trust the driver when they say a cyclist "came out of nowhere". Since these sorts of collisions are more often fatal for the cyclist than the driver, there often isn't anyone to tell the other side of the story. There are rarely criminal charges, and even more rarely convictions (juries are mostly drivers, not cyclists).
