I've had my Model 3 since March, and in general I think the human factors engineering is pretty good. However, I am amazed that the auto setting for the windshield wipers isn't cancelled when you leave the car. It seems to me that this is just asking for your to forget it's on when, on the next sunny day, you run the car through an automated car wash. Other cars I've owned with rain sensing wipers automatically turned the wipers off when you shut off the car.
