Maybe in the beginning Tesla had good engineers. Now those engineers left and the remaining engineers, well it seems they have no say to improve things or aren't that good. Tesla is constantly covering up all the issues with their vehicles. Elon has done his best to use political connections to increase sales and make it harder for competitors to compete. Even had Trump doing an ad for Tesla right infront of the Whitehouse. I wouldn't ever buy any Tesla manufactured these days, wouldn't even take it for free with all the safety concerns.
