The technology is unusable. I spent an inordinate amount of time trying to figure out simple tasks like how to lock the doors, open the trunk, or use the windshield wipers. The cars don't support Carplay, so I had to figure out how to log into some app on a touch screen. Eventually, after much frustration, I could get bluetooth to work so it could function like a car head unit from 2007.
Then the charging experience.
I was in Tucson, a metro area with a population of over a million people. There were two Tesla chargers TOTAL. What they don't tell you is those chargers don't support full charging speed when they are congested, so prepare for hour-long charging sessions. Which makes sense because the laws of physics, they don't have a nuclear power plant on standby to charge dozens of cars at 200KW.
The driving experience, was huge regression. I used to own a Bolt EV so that's my reference point for "cheap, utilitarian EV". I expected Tesla would be some kind of luxury vehicle. Wrong. These cars have the suspension of a base model mid-90s corolla, and the road noise too. The Model 3 was the loudest car I've ever driven, louder than modern pickup trucks.
Of course they failed. Anyone who has ever rented one of these things would pick up on it pretty fast.
