I drive an '03 Mercedes and I can tell you that the wipers are absolutely intuitive -- just like almost every other car I've driven, from back before the automotive design industry collectively lost their minds. Touch screens have never belonged in a car, and they still don't.

I’m not particularly interested in whether Tesla is more or less convenient than whatever Mercedes is up to, what matters to me is that is is undeniably less convenient than the standard lever toggle that has been around since as long as I remember. In my 2004 4Runner I can go to any wiper configuration without taking my eyes off the road (or even thinking about it at all), I can do the same for head lights, radio, cruise control, A/C, traction control, transmission toggles, etc. To pay $$$ for a “modern” car that makes every one of those core operations more difficult is, to me, absurd.

I'm not an absolutist about physical controls vs. touchscreens. Of your examples, A/C and traction control are automatic enough that I don't fiddle with them during driving and the touchscreen works great. As for transmission, the Model 3 doesn't have one. Radio, headlights (brights), and cruise control have physical controls that work just fine.

The wiper controls are really my only complaint. It wouldn't even require hardware changes to fix, as they could add a gesture involving holding the button while moving the stalk or something like that; they just haven't bothered, presumably because they think everyone should just rely on the auto wipers.

> The wiper controls are really my only complaint.

Back to my original point: the wiper control is arguably (see above) the single most important important manually operated safety feature in a car (besides maybe the breaks). For them to have such poor design speaks to Elon’s ability to put function over form.
