I think touchscreens could be fine, even in cars if they limited inputs to broad swipes. As for visuals it should rely on simple colors to encode functionality and provide feedback during operation.
The problem is feature creep where they want user to have so many functions that they have no choice but to use buttons and detailed graphics.
I think if the smallest buttons they used occupied at least quarter of the screen and if screen would have corners that you can physically grab onto when you are pressing they could be mostly fine-ish.
UX designers that design console experiences for visually impaired people would be the best people to create UI for cars. Although still not perfect.
