I'm not sure what the distribution is, but definitely both. I've been hit in an intersection, funny enough, by a police officer, who just turned right, crossing into the bike lane, t-boning me. A few months ago, I saw a truck completely just run over a bicyclist, killing her on 6th ave, and not even stop [1].

Often times, protected bike lanes are still very unsafe. 6th and 1st Avenues are a prime example, where trucks park to the right of the bike lane, and unload in the bike lane, forcing cyclists to suddenly merge into aggressive traffic.
