Touchscreens sometimes don't look good on very expensive cars, and gold watches because the touchscreens on car dashboards can look like a cheap tablets. The tablet's touchscreem software user interface don't look as good in highend cars and gold watches compared to silver or gold buttons, and knobs which have a more fancy design. If I were to buy a very expensive car, watch, or suitcase, I think having materials like wood, gold, silver, diamonds, and marble on it would make it look more highend than sticking a touchscreen on it.
I think most tablets and touchscreens built-into cars, smartwatches, stereo systems, speakers, and fridges is a gimmick. There are usually not many useful apps and games for it compared to a smartphone or tablet like an iPad is more useful, and have better apps/games, and faster performance compared to a smartwatch, stereo system and car's touchscreens computers which sometimes use a cheap slow CPU, and 1GB or less of RAM.
