Good change! The heat is sometimes too hot for the steering wheel and sometimes quite low. Strange. Maybe there is already a system capable of adapting the heat based on the interior temp.?
What would be extremely valuable and innovative would be a heating system for headlights (like the one for the windshield wipers).
Cars left outside at night in mountain areas are mostly iced, frozen in the morning and we systematically have to remove ice on the glass during several minutes outside while temp is really cold -5 to -10°C or less (with wind blowing... awful!
In the past, the heat of the lamps was enough to help ice smelting but with led, this is now impossible. Driving with iced headlights glasses is dangerous for other and the driver.
