My teacher and friends say that I am addicted to cars... Every time I look at cars they tell me to stop. I don't have any friends who are car guys, and nobody understands how I feel

I hate that I have nobody to talk about cars with in person, and that everyone thinks cars are stupid. I get nothing but hate when I talk about cars, but I don’t ever want to give them up. I know that it isn’t a problem, and it doesn’t really get in the way of school work, but I can’t convince my teachers, family, or friends of that. Nobody understands that cars are my passion, and nobody thinks that it is possible to care as much as I do about cars. Any time they ask me about a random car fact, I give an immediate answer, and they make fun of me for knowing those things. They have no idea why I would want to know the exact horsepower figure of the new Audi R8, or why I know about some of the most obscure cars. It’s getting hard to deal with it, because I can’t find anyone to talk about it with. My friends think that I am either addicted to cars, depressed, or both. Help from other car people would be greatly appreciated.
