>I feel like these crosswalks give people a false sense of security that they can cross without vigilance at any time.

Yes, if the walking-person symbol is on the thing, I expect to be able to walk without dodging these megaton deathtraps who want to be one minute earlier to the job they hate. I especially despise that cars are even allowed to turn into a street while pedestrians are crossing. What's the point of the walking-person symbol light if you're gonna allow cars to go through anyway during it? Dumb.
