If you don't believe me look at your local news. Granted they don't keep up the endless barrage of injured people, but deaths sometimes get a short mention. Police often fail to investigate these deaths, they just call this common occurrence a "tragic accident".
oops, you just killed someone. don't worry, it's not against the law...
This is due to a loop-hole that states pedestrians are responsible for crossing when safe.
“There’s no law on the books that we can point to to charge an individual who, without intent, negligently and accidentally injures a pedestrian, or bicyclist, or individual in their car.” SF DA spokesperson Omid Talai.

How did this and so many other absurd transportation anomalies come to be?
Well documented lobbying from the auto-industry decades ago.
