I'm in the same boat as you here. Level 2 and 3 are unsafe for me as an individual. When I drive, actively focusing on the road and driving keeps me awake. When I'm a passenger, the lack of mental concentration plus the gentle rocking motion of a moving car knocks me out within ten minutes.

The current Tesla autopilot is obviously working well for many people, but for myself I have to wait until level 4. Anything more hands on than that is inherently unsafe because of my habits.
