I've seen several videos of Tesla's autopilot getting confused by road markings and steering towards obstacles as a result. Using fewer sensors gives you less information, which seems like a bad idea for something as critical and difficult as automated driving on public roads. It's strange that Tesla's been getting away with unmet promises and dangerous behavior for years now.
