Tesla's wiper controls are ruled illegal in Germany after someone crashed while using them - Electrek I think Tesla can solve this issue through a software change; reprogram the button on the end of the wiper stalk so that a quick double press increases the wiper speed by one step, and once the fastest wipe speed is reached the double press decreases the speed by one step. That won’t offer total control of all wiper speeds through that button, but it will help. I find the Auto wiper setting works pretty well most of the time (though it’s not perfect) and the controls on the display are easy to use.
I also thought it interesting that the article didn't mention that you can adjust the wiper speed without taking your hands off the wheel using a voice command.
From what I read, the court did not find that the controls were illegal, but rather the driver failed to use them safely and crashed. He could have just as easily been messing with the heater or the radio.
