It's a small sample set, obviously.
When I see cyclists approaching a red light, I generally assume they will run it. I'm not judging this one way or the other; it's just what I've come to expect by observation. Usually they're polite and attentive enough to aim behind crossing pedestrians, but it seems that many feel they have an overriding right-of-way regardless of signage or signals.
The cyclists I've spoken to about this shrug it off as a necessary evil -- biking in NYC is difficult and dangerous, and meticulously following the traffic rules makes it more so not less so. And once you're accustomed to breaking the rules for safety's sake, you begin to do it for convenience's sake as well.
