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’d be fine with that tbh. as long as it doesn’t fuck with actual operability.
I don’t want manufacturer infotainment anyways. I want climate controls, audio controls, a good spot to mount my phone with known good software, and a 3.5mm jack for audio input.
