1) Updates are very frequent. The recent 360 modelling is quite good.
2) The experience of purchasing and after-sales service is very good. Although the delivery check is very careless but they offer free service all the time.
3) Battery life and charging are great, whether at home or on the road. The app preheating and the comfort of opening the rear cover are nice. Sentry mode is also good.
4) Autopilot works well on roads with decent visibility. However, it's very unsafe in some areas like snowy and foggy, and I've identified a pattern. I think Tesla should refuse to engage it in those situations.
5) The alert sounds are disastrous. Every alert is popping and clicking. This is due to a lack of envelope fade-in or fade-out during startup and shutdown. This is something that any sound engineer should understand in college Audio 101 course. Even a $1 plastic toy wouldn't have this issue. This can be fixed by firmware I think but this is a very amateur mistake.
It's not perfect, but at this price range it's hard to find a better alternative.
