A bunch of you are failing to admit that the Tesla way for essential controls is way more complex than it should be. You have to either press the stalk button for a wipe (which is fantastic user experience when what you're trying to do is prevent dry wiping), then you have to look away from the road to look at the screen to confirm which speed is selected, and either move your hand to the scroll wheel or to the screen (and in both cases to confirm what is selected you need to be looking at the screen, in a low-down position). Using the scroll wheel on its own to avoid the dry wipe scenario is slower than using the touch screen and still results in nags, IME.
This all stems from the idea that they could solve it all with AI, which they have abjectly failed at and had no back-up plan for. The wipers in the conditions on the M74 were absolutely hopeless and the frequency of intervention required was unacceptable, given that it's way more distracting than a simple stalk control could ever be.
