Okay, whats your point?
As I stated, you will rarely ever see Bill Gates taking pictures next to fancy cars or purposely showing off his fortune like guys like Dan Blizerian. Of course he has A LOT of nice things (cars and a home), but hes not posting pictures on Instagram or Twitter taking a selfie next to his cars (And if you can find a picture like that, its not really of the norm). And he tends to be very modest in dress and attire. He's been spotted countless times driving a ford Taurus and wearing a $10 watch
So, my point still stands.
There are many factors. Personality is one of them. Another thing is that you mention Dan Blizerian. Dan comes from money. Bill Gates built his empire. To make a fair comparison then you would take Bill Gates' son when grown and see what he does. That would only be fair--son vs son.
Bill Gates is flashy when he needs to be for instance, he used to or still does own a Bugatti Veyron...
He may drive his Taurus around town, which suits it's and his purpose.
Warren Buffett is not a "car guy"---he's an older man who likes the ride of the Lincoln Town Car and the big body Cadillacs. He would have someone but the cars for him. Yet, he invested in a Chinese Car company called BYD.
But, then you have those who see cars as an investment. Who do you think can afford those $40 million Ferraris and Bugatti Type 57s? The Ultra Rich.
I just think it's multiple factors involved.
