This thing happens almost every day, and is extremely annoying.

I'm halfway through the crosswalk on a walk light, walking at 3-4mph.   Then some car arrives at the intersection and instead of waiting their turn, starts turning left, through the same crosswalk, at high speed.  They seem to time it so that they just barely miss me by a foot or two.   Sometimes I have to accelerate to get out of the way.   This feels extremely disrespectful.   People who do that are scum.   They shouldn't start turning until the way is completely clear.
