Tesla

Almoat every car maker out there makes constant changes to their products, releasing new editions or overhauls of existing cars year over year. Some smaller car companies, like luxury or hyper car makers, may take a few years between new models. Tesla is the only car company that is using the same hardware and designs from over a decade ago. Phones have evolved more than Tesla designs, and that shit hasn't significantly changed since touchscreens emerged.

And that's just their cars. Electrical systems like solar tiles and on-site battery systems are the same as when they were released, with the exception of Power Wall getting a lateral update between Power wall 2 and 3.

Tesla is devoid of innovation and has given up on QA to sell as much as they can before the company is considered obsolete and irrelevant.
