The Globe and Mail reports in its Thursday edition that Tesla is recalling over two million vehicles in the United States to install new safeguards in its Autopilot advanced driver-assistance system, after a federal safety regulator cited safety concerns. A Reuters dispatch to The Globe says that the largest-ever Tesla recall appears to cover nearly all vehicles on U.S. roads to better ensure drivers pay attention when using the system. Tesla's recall filing said that Autopilot's software system controls "may not be sufficient to prevent driver misuse" and could increase the risk of a crash. The National Highway Traffic Safety Administration (NHTSA) spent over two years investigating whether vehicles produced by the electric carmaker adequately ensure that drivers pay attention. NHTSA's Ann Carlson praised Tesla for agreeing to the recall. "One of the things we determined is that drivers are not always paying attention when that system is on," she said at a U.S. House hearing. Ms. Carlson said the agency opened a safety probe in August, 2021, when she kept hearing about fatal crashes involving the use of Autopilot. Separately, Transport Canada said Tesla will recall 193,000 vehicles to address the Autopilot issue.
