US report: nearly 400 crashes of automated tech vehicles

Automakers reported nearly 400 crashes of vehicles with partially automated driver-assist systems, including 273 involving Teslas, according to statistics released Wednesday by U.S. safety regulators.

The National Highway Traffic Safety Administration cautioned against using the numbers to compare automakers, saying it didn’t weight them by the number of vehicles from each manufacturer that use the systems, or how many miles those vehicles traveled.
