Follow-up: teach them to learn to troubleshoot and search. Take the fear of breaking something from them by providing them with a VM with windows where they need to fix something or install a driver. Provide them with a Linux VM just for them to try too.
Teach them mistrust. Make them upload things to a copy of Google docs or something, and then show how you have access to everything.
Teach them about open source as a precondition for being able to trust software.
For racing, you have Fly Dangerous. It is also a successful FOSS game!
