I believe this is no longer true (though it was for a couple of years). I own a T3. It has many wildly incomplete and "buggy" behaviors which were all forgivable when this was the only game in town. Now I'm actively looking forward to an electric Audi or Merc or VW or Ford or... the list is growing rapidly.

Just the fact that there's no way to disable the car's insanely buggy (and almost always wrong) auto-steer feature which slams on the breaks or steers wildly left or right when the car (again - WRONGLY and NOT WHEN ON AUTOPILOT) decides (did I mention "WRONGLY") that there's some hazard that it (incorrectly) feels the need to (suddenly and without any obvious reason) needs to (spontaneously) avoid? Oh, and don't get me started on how last winter the heat pump went out (on thousands and thousands of 3s) here in Quebec when the temperature dropped to -30º and the windows fogged over and froze and I was left stranded on the highway an hour from home and Elon Tweeted "we're working on it"... TWO WEEKS LATER and you know when they fixed it? Never. They implemented a kludge and now the car pumps luke warm air and it's sorta' kind'a driveable but still the temperature in the cabin is about 36Fº - which sure - it won't kill you but... you know... not very "luxury" feeling. And you know what other E cars have this problem? None of them.

I don't mean to be dunking on you in any way... Just trying to keep things in perspective :)
