I don't mind if cars drive through on the walk phase as long as they slow to a crawl and make sure no one is walking first. Sometimes the road is very much clear because the person has already crossed, there's no need to hold up the cars.

And I say this as a pedestrian, I walk to work. And I am afraid of getting hit every day but for a different reason. The crosswalks are in the stupidest friggin spots, around a bend in the road, and cars are apparently allowed to park right up against the crosswalk so if even want a hope in hell of being seen you have to walk part way onto the road, and peak your head around the van that's blocking the view for both you and oncoming cars, and then hope they can see you around the bend in the road.
