* They could integrate it with the vehicle's aesthetics better so that it looked fundamentally attractive.
* They could use a better backlight, better ambient light sensors and darker graphics so that it wasn't distracting at night.
* They could improve the passive screen state experience so that it was never ugly or distracting.
* They could use separate screens vigilantly so that touch interfaces are near to hand and notifications (e.g. volume changes, navigation, incoming calls, etc) are exclusively shown on a screen near the driver's forward vision.
* And most importantly, they should have physical controls for all common actions. You shouldn't ever have to touch the screen while driving. (Looking at you, Telsa.)
Instead, they attach actuators and mechanisms that are guaranteed to break, probably in the closed position, and you won't be able to use most of the car's functionality until you pay for an expensive repair. Embarrassing.
