Missing High School Education

There are a few subjects that I think were missing in the high school curriculum. They are household finances and general automotive maintenance. I think these two subjects should be a part of all teenagers' education because it is something that every person will need to know.

For instance, would it be so hard to teach teenagers, especially women, how to change oil (or check oil for that matter), do a tune-up, change a tire, etc? They should teach general maintenance/repair that would give them the knowledge to not only take care of their own vehicle but know when a mechanic is cheating them. They don't have to teach them what coilovers are or anything really technical but I think these two subjects are truly things that you would use in life. How many times did we ask ourselves in high school while struggling with homework why we needed to learn something in particular? I know I did, especially in geometry and while we were dissecting Garfield.
