I didn't realize how good Teslas had gotten until I had the chance to spend significant time in one. Their insane acceleration was always apparent, but they've gotten really good in other ways as well.
They've had a chance to do a clean sheet rethinking of cars, and it works wonderfully well. If you have your phone on you, you just walk up to the car and the door is unlocked and on by the time you touch it. There's no "start" button, you just press the brake, push the mode stalk to drive or reverse, and go. When you walk away, the car locks itself silently and turns off. Depending on whose key it depends, the seat, steering wheel, and mirrors are adjusted by the time you sit down.
There's no "idling" to keep the AC on, so there's no guilt about doing it. They've recently added a very efficient heat pump that shares loops with the battery so the heat doesn't drain much, either. We spent an hour in the car with AC on recently, it used about 1 mile of range.
I thought I'd hate the touchscreen controls, but what I didn't realize was that you generally don't need to use them while driving. Wipers and climate are automatic and work well, so there's no real need to adjust them. The voice control is incredibly good, and seems to have access to almost every non-driving setting. Press a button on the steering wheel, and speak "Set wipers to auto", "I'm cold", "Play Spanish Moon by Little Feat", "Navigate home". They all work as you'd expect.
Jury is still out on "autopilot", lane following and dynamic cruise control are fine, but the onscreen world representation (cars, especially) is very jittery. I guess not too surprising, it's a DNN making guesses about the state of the world, but I'm surprised there's not a more persistent context vector between states. If it's very sure about a car being there in frames 1-10, it should really not expect that car to just blip out of existence in frame 11.
But overall, I'm extremely impressed, and I think I'll have a hard time going back to cars by traditional automakers. The impression is of a holistic design that's extremely well integrated, rather than the impression of a hodge podge of poorly integrated new and old systems that I've gotten with any car with an "infotainment" system that I've ever used.
