Tesla did not release new cars, except for Cybertruck, for how long ? 5 years ? 10 years ?
Their lineup was great initially, and there was 0 competition. Now there is a lot of competition and their lineup did not change at all.
Their car business is dying. That's why they try to be an AI & Robotics company.
Edit: Here is a good link to follow the sales data - for many countries, it's reported daily. https://eu-evs.com/brandCharts/TESLA/ALL_DAILY/QoQ-Chart
