Autonomous car safety rules get a long-overdue NHTSA revamp

The rules for autonomous cars in the US are being updated, with the NHTSA announcing an overhaul that addresses driverless vehicles with no traditional controls, and AVs that aren't designed to carry people at all. Billed by the National Highway Traffic Safety Administration as an "historic step" that should help remove regulatory barriers to deploying autonomous vehicles, it also exempts some types of AV from certain crash-testing.
