wealth and stupidity come hand in hand in many, many cases.
I think this is partially because in order to make a lot of money in most cases you have to fuck someone else over and never have it occur to you thats what you're doing. Like if you find out you can buy t-shirts for €1, then you go to your neighbor and tell them they can have a t-shirt for the low price of €30 (and manage not to feel bad about that) you're a successful businessman and a pilliar of the community.
Cyber truck buyers are Elon worshipping tech bros, which means that they think they are smarter and better than everybody else. This leads to acts of hubris like the above picture, which are obviously very stupid and easy to see coming, but these types of people think, "I am very smart and know exactly what I am doing at all times. This will be fine, because I am doing it."
