The National Highway Traffic Safety Administration announced a new “voluntary national framework for the evaluation and oversight” of autonomous vehicles, a bureaucratic first step that could eventually open the floodgates for fully driverless cars. But there’s a twist: the agency wants self-driving car companies to cough up more data.

Currently, no federal regulations specifically govern autonomous vehicles, leaving oversight to individual states. Self-driving cars, however, are still required to comply with general federal safety standards applicable to all passenger vehicles.
