Even though other manufacturers may not be reporting these numbers, Level 2 ADAS systems are pretty common as far as I can tell. Wouldn't any vehicle with adaptive cruise control and lane-keep assist be considered Level 2 ADAS?
> ADAS that are considered level 1 are: adaptive cruise control, emergency brake assist, automatic emergency brake assist, lane-keeping, and lane centering. ADAS that are considered level 2 are: highway assist, autonomous obstacle avoidance, and autonomous parking.

I think that Level 2 requires something more than adaptive cruise control and lane-keep assist, but that several automakers have a system available that qualifies.
My intuition is that there are more non-Tesla cars sold with Level 2 ADAS, but Tesla drivers probably use the ADAS more often.
So I don’t have high confidence what tesla.mult should be. I wish that we had that data.
