They do not cause anything. The cause is the driver choosing to pay attention to the devices.

I find the touch screens distractive. You have to look at the device and work through the menu system to get to the function you want. I’ll take knobs and pushbuttons anyday!

You cannot put an intrusive* device in a car that the driver is not used to seeing or hearing, and then expect the driver to ignore it. The ergonomics of the driver and the car are critical to the safe function of the vehicle.

* When I say "intrusive" I'm referring to an audible or visual warning that is designed to capture the driver's attention and therefore can't easily be ignored.
