There are a two things I take away from this.
If you are fiddling with your touchscreen (regardless of car) then you are not focusing on the road. Having said that every other car I have owned did not have any features that were required to drive safely actually hidden away in your touch screen menu.
I had a look at a video showing how the wipers are operated on a Tesla Model 3, and sorry but it really is made more complicated than it needs to be. If such a fundamental feature is only accessible by touchscreen then that really is a poor ergonomics choice. Yes you can press the button to wipe once, or use the voice control but I think this points out the flaw with Tesla's (and to a lesser extent, other brands) love affair with technology. Tech is not the answer to a problem that never existed, especially when it is actually counter-intuitive.
I feel the same about the pointless touch screen temperature controls on my E-Tron. Though at least they are not a fundamental feature for driving the car safely or reacting to changing weather conditions.
