Both lane assist and backup cameras are mandatory safety systems for new cars in the EU. Same goes for things like tired driver detection and other stuff that was considered opulent luxury ten years ago.

With the land tanks we call SUVs today, I can imagine it wasn't hard for politicians to decide that mirrors are no longer enough to navigate a car backwards.

Still, you don't need touch screens. Lane assist can be a little indicator on a dashboard with a toggle somewhere if you want to turn it off, it doesn't need a menu. A backup camera can be a screen tucked away in the dash that's off unless you've put your car in reverse. We may need processing to happen somewhere, but it doesn't need to happen in a media console with a touch screen.
