Could it be that Musk's inflammatory language and behaviors are a turn off for potential buyers? They are a turn off for me. I like the vehicles but I'd never get one.
This seems to be the case for some online communities, but in my offline circles (Asians working in tech in the PNW) no one seems to care. Driving on the street it seems every other car is a Tesla, and by and large everyone is pretty happy with them. I wouldn't say we're particularly pro-Tesla either, it's just that they were the best cars for the money at the time. As more car manufacturers start to deliver good EVs…
But talking with some of the Tesla owners, many feel embarrassed by Elon. Many say that they will not buy another Tesla or they have some other reasoning to justify their purchase (like Elon has gone crazy but we shouldn't punish the entire company for it etc)
