Highlighting some parts of my previous comment you may have missed: > When the light changes, or you're in the right turning lane, sure you need to go over the crosswalk, but that's not what I'm talking about. I routinely are drivers going straight or left pull into the crosswalk. It may be more visible/memorable to me because I do a lot of walking, so they're often in my way. I don't know your situation, but if you're mostly driving, it may not be visible to you (because you're not at the front of the queue) or memorable (because it doesn't cause you to change your route). I see people do crazy things all the time just out of impatience. People even fully enter the intersection sometimes (when they're going straight and have a red, and people turning currently have a green arrow), it's nuts. And then people will pull up behind them, locking them in. So if someone ran a light, there would be no way to avoid a collision. (Obviously you shouldn't run lights either, but people do.) My philosophy is that any complex system can suffer at most 2 faults without a failure (as a rule of thumb). So when people push the boundaries like this, they're expending the buffer we need to avoid collisions caused by honest mistakes. If someone pulls into the intersection, someone pulls behind them, and virtually anything else goes wrong, there will be a collision.
