The robotaxi law that could ban Tesla

For more than a decade, one question has loomed over the race to build autonomous vehicles: Are cameras alone enough to safely replace human drivers, or do truly driverless cars need additional, overlapping sensors like lidar and radar to navigate the world reliably?

Tesla has bet billions of dollars that artificial intelligence and cameras are sufficient. Nearly every other major autonomous vehicle developer has gone the opposite direction. Until now, that argument has largely been left to executives and engineers.
