What works:
- best in class software quality. Both various controls (lights, wipers, electronic parking brake etc.) and infotainment work just right.
- Navigation is quite good, especially considering it automatically adds/ suggests charging locations as needed.
- Steering assist (automatic lane and speed control) is quite handy. I never felt the need for trying out autopilot.
What doesn't work: it's just one thing for me: you cannot trust Tesla:
- Battery mileage. My model Y is supposed to give me 330miles on a full charge. For the recommended 80% charge it should be ~260 miles but in reality, I get 125 miles in winter and 200 miles in summer.
- Price drops. Cars depreciate but to have a $10-15K price drop right after I purchased really sucked. For this reason alone, I will never buy a Tesla again.
- For a 70K (model Y) car, it rattles, and they will charge 30$ to test for rattling.
- I haven't faced them but I often read about poor quality issues like cracked roof, wheels falling off (yes !).
