Modern mazdas are one example - the touchscreen locks out above 5 miles per hour.

This is only feasible because the physical controls are excellent, and you can basically accomplish anything except typing an address or a song name without the touchscreen as input.

The newest CX-5, their best selling car, abandons the knob, if that’s what you’re referring to.

Supposedly most buyers in fact, did not like the knob.

This seems to follow other manufacturers that formerly had knob based controls but similarly abandoned them.

I have a new Mazda with CarPlay, you can touch the phone at any time? Or are you referring to the "extra" touchscreen on some models in addition to the control knob.
