TLDR: They’re not ruining it, as they’re enjoying in their way. It’s the people who watch them that usually ruin the scene for others.

I‘m not saying I defend trust fund kids but I won’t attack them neither.

I think it’s more of a lack of „standards/taste/maturity“ of the whole car community in general.

On one side, people with money can afford to care less about their cars as they are more easily replaced/fixed, and yeah, for those who cannot afford a car (like me) and would love to have a garage as diverse as the one you mention (because I know who you’re talking to) it’s basically seeing something you love being destroyed. They also realise they can do such stuff and just upload it to YT and share and have millions of views and maybe build something profitable out of that exposure, but at the end of the day, they are doing what they want with the things they have.

On the other hand, I think most people lack standards on what is cool but shouldn’t be done and what should. I agree that sometimes it is painful to see them not giving a flying f- about people, rules and so on, but also most of them do such stuff understanding the risks and trusting in their skills. The problem comes when you start comparing your situation with theirs, which ultimately leads to jealousy or resentment because you would do things differently as the ones the YouTuber does.

To name a few examples: It’s like car collectors watching people buy rare cars and actually use them, should they be angry because of it? In their eyes and reasoning yes, because for them it would be like using the Mona Lisa as a dining table cloth, but on the eyes of the ones who drive them they think of the other party as „dumb“ for not enjoying their cars, according to how they think of it.

The trust funded people you mention are, yes, normally „out of touch“ for ruining a ski slope, but also we as viewers don’t get to know the whole backstory of how they got there. Was the ski slope at the end of the season? Was it being repaired on? Was it a perfect slope and the owner decided to make the event and let people drive their cars up because it’s fun?

What I’m saying is, For taste there are colours. You like what you like because of how you think, and so do the other people. We watch car content because they do what the most of us can’t do, like in a movie. I do think there are a lot of things done only for the content and don’t actually think about the repercussions, and that should change, but people aren’t perfect, and although some of them can be pardoned, others should be stopped.
