My Tesla Model Y works great. As an "appliance" I am super happy with it.

Most other smart appliances I've used, however, have not created joy in my life, and I try to buy the oldest and dumbest appliances I can. For our new oven last year, we specifically looked for something with real knobs and an LED display, zero smart features. (Viking is the last company that makes these afaict.)

Turns out software is hard, if you're gonna make a smart appliance you have to build an entire software company. Tesla managed to do that but not other companies have.
