According to a report by The Washington Post, Elon Musk overruled a significant number of Tesla engineers who warned him that switching to a visual-only system would be problematic and possibly unsafe due to its high risk².

This resulted in an uptick in crashes, near misses, and other embarrassing mistakes by Tesla vehicles suddenly deprived of a critical sensor².
