Because it can be trivially duplicated, this is minimally capable engineering. Yet automakers everywhere lack even this level of competence. By reasonable measure, they are poor at their job.
(another reason was because it still has a geared transmission instead of a CVT, but that's a separate discussion)
A friend got a tesla on lease and it was quite cheap, 250/month. Been driven in that car a few times and was able to study the driver using the controls and it’s hideusly badly designed, driver has to take eyes off the road and deep dive in menus. Plus that slapped tablet in the middle is busy to look at, tiring and distacting. The 3d view of other cars/ pedestrians is a gimmick, or at least it looks like one to me. Does anyone actually like that? Perhaps im outdated or something but I wouldn’t consider such a bad UX in a car.
In practice many drivers seem to be dealing fine with the touch screen because they've stopped paying attention to the road, trusting their car to keep distance and pay attention for them. Plus, most of the touch screen controls aren't strictly necessary while driving, they mostly control luxury features that you could set up after pulling over.
