Yep, Tesla's share of the US EV market had fallen, but they are still #1 by a long shot. Competition has emerged and grown, and as you say, Musk shot himself in the foot with his recent actions, which I believe are contrary to his fudicial responsibilities to his companies.I have read that Tesla sales have fallen almost 15% - while general sales of EVs are up.
I believe Musk getting openly/publicly involved in politics, was a very poor business decision.
"Cool" is a very subjective label.
I believe GM became #2 is US sales in 2024, and had a strong 2025 Q2.
I didn't bring up cool.
