NHTSA is investigating whether Tesla's "autopilot" system has trouble detecting emergency vehicles with their lights flashing (and thus is more likely to hit them). Cruise might have a similar perception problem.
"Since January 2018, the Office of Defects Investigation (ODI) has identified eleven crashes in which Tesla models of
various configurations have encountered first responder scenes and subsequently struck one or more vehicles
involved with those scenes. The incidents are listed at the end of this summary by date, city, and state."
"Most incidents took place after dark and the crash scenes encountered included scene control measures such as first
responder vehicle lights, flares, an illuminated arrow board, and road cones. The involved subject vehicles were all
confirmed to have been engaged in either Autopilot or Traffic Aware Cruise Control during the approach to the
crashes. "
