An anonymous reader writes: In response to the third reported Autopilot crash, which was the first of three where there were no fatalities, Tesla CEO Elon Musk says that the Model X's Autopilot feature was turned off. He tweeted Thursday afternoon that the onboard vehicle logs show that the semi-autonomous driving feature was turned off in the crash. "Moreover, crash would not have occurred if it was on," he added. The driver of the Model X told police he was using the Autopilot feature, according to the Detroit Free Press. The vehicle flipped over after hitting a freeway guardrail. U.S. auto-safety regulators have been investigating a prior crash that occurred while Tesla's Autopilot mode was activated. Late Thursday afternoon and into early Friday, Musk made some comments on the improvements made to its radar technology used to achieve full driving autonomy. "Working on using existing Tesla radar by itself (decoupled from camera) w temporal smoothing to create a coarse point cloud, like lidar," he tweeted. "Good thing about radar is that, unlike lidar (which is visible wavelength), it can see through rain, snow, fog and dust." Musk has rejected Lidar technology in the past, saying it's unnecessary to achieve full driving autonomy. Consumer Reports is calling on Tesla to "disable hands-free operation until its system can be made safer."
