touchscreens in cars work, because the evidence says so...
"Using the center stack (e.g., touch screen, knobs/button built into the dashboard) was less demanding than using voice commands, which were less demanding than center console (e.g., writing pads and dial) interactions." Visual and Cognitive Demands of Using In-Vehicle Information Systems (2017). AAA Foundation for Traffic Safety.
Nice to read:
Yes, it is necessary to keep improving the interface and make in-car interactions easier and safer. However, the fact that touchscreens, and their graphical interface, are not perfect should not lead us to statements that are not supported by evidence. As of today, touchscreens are the best interface and statements such as "touchscreens in cars don't work" are dangerous and misleading.
If you have the evidence that states otherwise you are very welcome to challenge, However, not all evidence is the same, a study you did with your mates on your Playstation hasn't got the same quality as a well controlled study conducted by an academic institution. And please don't consider your opinion to be as important as the evidence. You can say "I don't like touchscreens in my car" that is absolutely fine, but you can't say "touchscreens don't work in cars" because you, and some of your friends, don't like the touchscreen in Tesla.
Back to the evidence-based product development, one of the best studies so far to investigate visual and cognitive demand of infotainment systems is the one commissioned by the AAA Foundation and conducted by University of Utah. They tested 120 people (54 females) aged 21-36 years old (m=25). This was an on-road study using in total 30 vehicles and use cases included a) Audio, b) Phone, c) Text messaging and d) Navigation.
