In fact, Euro NCAP agrees. If you want a 5-star rating, you need physical controls.
The only people who want touchscreens are the car manufacturers, because it's cheaper and easier.
Your comment is applying a headline to something that isn't at all under discussion. The Euro NCAP says if you want a 5 star rating a bunch of core controls must be available as touch control. Currently it looks like it will affect 3 makers of cars on the road, Tesla (the functionality of windscreen wipers can't be managed without the touchscreen), VW who on a small set of their models put capacitive touch sensors on the steering wheel, and Volvo (by extension Polestar) who for some reason made the hazard indicator button a capacitive one.
No one will loose a 5 star NCAP rating because of a large touchscreen. They will lose it if any of the following aren't physical buttons:
- Indicators (turn signals)
- Hazard lights (emergency flashers)
- Horn
- Windscreen wipers
- eCall SOS function (emergency call)
HVAC, Sound system, navigation, all of that isn't included.
By the way I very much do want a bigger screen in my car. It makes it easier to see navigation reducing the time I take my eyes off the road. For the few touch related activities (not that I do many because the voice recognition in my car is excellent) it also makes it easier and more forgiving to have *big* touch buttons to press. Big screens are better for safety than small screens.
Also all of this is irrelevant. Cars have computers with RAM for reasons other than touchscreens.
