The regulation calls out 19 vehicle functions which must have physical controls inside the vehicle, with additional requirements about size and usability of the buttons.
Those functions include:
Turn signals
Hazard lights
Horn
PRND gear shifter
Driver assist function, if present
Windshield wipers
Windshield defroster
Power windows
Emergency call system
Power off switch for EVs


I didn’t imply otherwise, I just called it a shame.
Yeah, if only we had physical controls that we could use without taking our eyes off the road or even thinking about it.
And I am providing a reasoning why they choose those but not AC.
Because it is not essential to driving, it could be seen as an overregulation to require that
I think being able to see out of my windshield instead of having it fog up is pretty essential to driving
Defogger is physical
This person doesn’t know about driving, because they’re clearly 12.
