I'm glad to see JSO stepping up enforcement. It is a wonder that Jacksonville doesn't have more (than our already ridiculously high) pedestrian fatalities. Over half of the pedestrians downtown seem like they have no idea what crosswalk signals (or traffic lights) mean--even when walking with small children. Virtually everyday downtown, I see pedestrian step into oncoming traffic without even looking.
Again, every day, at least one pedestrian will step in front of me right as the light turns green (and their crosswalk signal has been red for 30 seconds)--fine, I'll wait for them. But then they step into the next lane (think State, Union, Main, etc.) where a car that has had light priority for several blocks is going 40-50 mph and cannot see the pedestrian until he/she steps out from in front of my vehicle.
Also, I routinely see pedestrians strolling across the street in the face of oncoming traffic, forcing several lanes of traffic to slow down or stop completely for them. This is not a real bother to me, but I can see how it could antagonize many drivers into not respecting pedestrians even in situations where the pedestrian has the right-of-way.
Again, it's a miracle that we do not have more pedestrian deaths in Jacksonville. I'm all in favor of walkable urban environments, but I have never been to a city where pedestrians are so ignorant (or uncaring) about traffic laws and basic safety.
