Somewhat ironically, the physical controls for the turns signals are by far the worst part of the whole Tesla UI. I've had my Model 3 for over two years now, and I still cannot reliably cancel a turn signal, or "soft push" the signal so it only blinks 3 times. It's infuriating to inadvertently signal left, then right, then left again, as you frantically try to just cancel the turn signal. I'm broadcasting confusion and incompetence to the outside world, when inside the car I know exactly what I'm trying to do.
