I really think that as part of any mediated agreement, or failing that, a judgment at trial would be that Tesla provide more data on our cars to us from the touchscreen. Most ICE cars have gauges for oil pressure, radiator temperature, and 12V battery charging/discharging. Idiot lights went out of favor in the '70s-'80s. And Tesla does not even supply idiot lights! (Yeah, I get the cold battery notice at 20% when I put the car in park.)
We should be able to pull up battery temperature, Supercharging efficiency (for lack of a better term), and overall battery cell readings. Too bad if the Service Centers get inundated with calls from ignorant owners. A brief explanation to accompany these data would help out a lot.
