I'm a only a single data point, but: I was recently in the market for a new EV, and the biggest reason that I didn't go with Tesla was Elon. Full stop.
and you are not the only one, i'm sure. You have a valid viewpoint.
Also, not everyone makes their car/EV purchase based on who Elon is. Some might care more about the car itself and how it competes with others. Some might not even know who Elon is, or what he's done on twitter.
Funny that the linked blog author whose company produces a very popular investing podcast (compound and friends) like to say only boomers answer surveys. Only just recently (last or previous episode) they found a hilariously large discrepancy between surveys and real world data. Surveys are probably the least reliable and least accurate data sources. You can't trust them to be even directionally correct.
Knowing who Elon Musk is and what he does is a mixed blessing. On the one hand, I know better than to give my money to that asshole. On the other hand, that asshole is constantly taking up space in my head. On the gripping hand, both of those standpoints are, more or less, useless.
