The car is a pleasure to drive — you don't want to get out. The navigation guides excellently, but Polish names are mispronounced. The car doesn't have cornering lights. The matrix headlights are very good.

I've done 6,000 km and I'm delighted. I haven't tried other EVs, but I'm thrilled with the BYD Atto 2. It's true I don't go on long trips — I do everything in the city and nearby, about 100 to 150 km a day — and honestly it's been great in every way. When I hit 300,000 km I'll tell you again. Haha
