TL;DR — No.
> We do not know of a single case of a cyclist fatality in which the driver was prosecuted, except for D.U.I. or hit-and-run.
That sure sounds to me like society has de facto decided "It's OK to kill cyclists as long as you aren't drunk and you stick around to apologize afterward."
When I said "No." I meant it's ethically wrong to kill cyclists, and not "O.K". I was merely answering the question posed in the title. I agree my use of "TL;DR" probably made sure everybody took this the wrong way, and was technically out of place, too.
