Once people sit and drive in a Tesla, they want a Tesla - even if they don't say it in public. It's just the hip and cool toy!
You know I think there's a fair amount of truth in that. I think a bit part of what prevents ppl from taking the leap is psychological -- they don't want to be seen as sticking out and doing something different, they're constantly worried what others think, and don't want to make the transition till the image has been fully validated by Hypebeast or Drake or something.
I've distinctly noticed jealousy in two of my coworkers since getting my M3, and they both make enough money, and I wouldn't generally classify either of them as overly jealous or insecure. But this car makes them that way, I've found it a bit odd...leads me to think they really want it, but are afraid of judgement.
