U.S. safety regulators have pressured Tesla into recalling nearly 363,000 vehicles with its “Full Self-Driving” system because it can misbehave around intersections and doesn’t always follow speed limits…
Raj Rajkumar, a professor of computer engineering at Carnegie Mellon University, doubts that Tesla can fix all of the problems cited by NHTSA with a software update. The automaker, he says, relies only on cameras and artificial intelligence to make driving decisions, a system that will make mistakes.
“Cameras can miss a lot of things,” Rajkumar said. “These are not straightforward issues to fix. If they could have fixed it, they would have fixed it a long time back.”
Most other companies with self-driving vehicles use laser sensors and radar in addition to cameras to make sure vehicles see everything. “One sensing modality is not perfect by any metric,” Rajkumar said.
