You should definitely start with small projects to build experience. Modern passenger vehicles are extremely complex. To get a feel for this complexity, it would be a good idea for you to start doing basic maintainence on your own vehicle if you have one (oil changes, tire rotations, etc). Invest in some good quality tools if you can afford it.
I knew very little about cars until a little over a year ago when I started watching Garbage Time. This YouTube channel is a very entertaining way to inadvertently learn every aspect of how cars work. Because of this channel, my partner and I have started doing all of our own car maintainence and we fixed a very poorly maintained Toyota Celica that had a spun bearing.
If your goal is to actually design and build a fully open-source passenger vehicle, you may want to collaborate with Open Source Ecology. I believe they already have an open-source truck in the works as part of their Global Village Construction Set.
Their goal is to create an open-source version of civilization's 50 most important tools. This is an extremely ambitious goal, but it's technically possible given enough time and effort.
Awesome thanks again for all of this Cobalt! Glad you got to get into maintainence/creation of all kinds of things yourself too.
Let's make all kinds of fun things!
