Every city and town does its own traffic engineering. A PKI to hierarchically delegate and validate all of those users? Bigger than anything else ever tried. Probably doomed to failure. Assuming that spoofing can be done...
Here's a fun thing not to try at home: a beacon on your own car that claims to be a portable traffic signal. "Lane closing; keep right."
"I'm a police car, let me pass."
Wayze likes to route vehicles through quiet neighborhoods as shortcuts. Drop a spoofer on the corner and the road is "closed" or "5 MPH" and stops being used as a shortcut.
"Invisible construction area, wait for [nonexistent] flagman."
