Opinion: please make touchscreens simpler, and give us the knobs back

I tested seven cars this year. Four of them hid the temperature control behind a screen.

A knob you can find without looking is a safety feature.

Physical knobs for volume and temperature let you keep your eyes on the road. A study by a fictional safety council found that adjusting the climate control on a touchscreen took 4.1 seconds, against 1.2 with a knob.

Carmakers saved money by removing the buttons. Drivers pay the price.

This is a demo story: every name, place, organisation and figure in it is fictional.
