New Footage Shows Tesla On Autopilot Crashing Into Police Car After Alerting Driver 150 Times

This is a most excellent place for technology news and articles.
I find that it can be hard to tell when a car ahead is stopped, maybe the visual system on the tesla has similar limitations. I think autopilot is controlled by the cameras alone but I'm not super up to date on tesla stuff. I would assume even a basic radar set up could tell something was stationary from quite far away.
