I mean, cars can be demystified the same way computers can: By building and maintaining it yourself. Everyone is afraid to build their first computer, because it seems way too complicated and delicate. Then you actually build your first one, and go “oh hey this actually isn’t so bad after all.”

Yes, cars (especially modern cars) have a lot more difficult-to-build parts. But modern cars are also a lot like computers in the sense that you don’t need to know every single component on an GPU to be able to install one. You don’t need to be able to build a car part from scratch. The same way you can slot a GPU into a motherboard, you can just buy the entire car part preassembled and bolt it into place. The important part is learning what the different components do, so you can troubleshoot them.
