We should NOT have touch screen interfaces in cars. Full stop. If the driver has to divert their gaze from the road to operate e.g. the heating/AC[0], that is a failure of UX sufficiently egregious to keep the car off the road. It is not a toy, it is not a fashion statement, it is a thousand pound chunk of steel that will indiscriminately kill and maim if not operated with care and diligence.
[0] This is the complaint I have with my wife's Honda Civic. If I want to do something as simple as turn on the fan but turn off the AC, it means navigating into a sub menu and correctly hitting one of several choices on a touch screen.
