If you thought that officials would halt progress on self-driving cars in the wake of a Tesla Autopilot crash in May, you're in for a surprise. National Highway Traffic Safety Administration lead Mark Rosekind told guests at an event that he and other regulators don't plan to slow down the development of autonomous vehicle hardware. To him, the car business "cannot wait for perfect" -- people have to be "desperate" for any technology that could save lives. He isn't touching the Autopilot crash specifically (the NHTSA is still investigating), but it's reasonable to say that he doesn't currently see the tragedy changing his stance.
