I would also add that Tesla's sensor systems, while perhaps higher quality, are not exactly new ideas. In one form or other laser/radar-based systems have been in cars going back to the 90s for early collision avoidance, automatic cruise control, etc.[1] Longer in other applications.

At least one study seems to suggest those sensors when deployed in automatic emergency braking systems do have a measurable impact on collisions.[2]

Let's say the failure rate on the sensors was 1 in 100 (I'd be shocked if that many were defective). That means 99 other Teslas are using mutli-sensor systems and not driving with degraded capabilities. It's an asinine claim that doesn't pass basic logic tests. The only way they weren't a substantial improvement is if Tesla's measurements were conducted in only the absolute most ideal conditions for cameras and no other scenarios.
