I didn't know about that. I don't blame them for just running them on occasion. I jwalk, but that is a bit less dangerous than flying through a red light because you think no one is coming. Most bikers don't stop let alone wait for 10 seconds.
1. Jaywalking is rare % wise. Most of the time I see people who jaywalk, do so very carefully. The worst of pedestrians that I see are the ones who ignore pedestrian lights without reguard for traffic or the ones who stand in bike lines.
2. Most cyclists either weakly obey rules, or flat out disregard them. (weakly, as in they'll wait in the crosswalk or fail to yield to pedestrians) The majority of the time that I see a biker on the sidewalk (above 18, by law it's 12+ you're not allowed to bike on the sidewalk) I'll point out where the road is to them and the response is "fuck you".
In my experience jwalking definitely is done in 99 percent tile with complete situational awareness. most cyclists really do obey laws or ignore them when safe. Which is understandable, I've run red lights when no one is around.
But what does piss me off is nearly getting clipped by a biker on the sidewalk. I've never seen a person under 25 riding on the sidewalk. And for some reason it seems to be a guy with a beard and fixed gear bike.
I frequently see people from about 20-40s riding on the sidewalk. It's rare to see an under 12 or a senior citizen riding on the sidewalk. Although I did get told "fuck you" by a middle age guy when I pointed to where the road was. (He and his wife were riding on the sidewalk).
From my experience, it's rare to see a cyclist obey traffic laws. I'm just shocked to see them even use hand signals. (The better explanation for that is that I'm hallucinating it's that rare)
