I actually have a version on my computer with vehicle as a module but then didn't upload it. was debating uploading it. I thought the assignment was to make it all in classes so then I didn't upload it. But perhaps I should show it too.

I was looking at the needs_gas and didn't like how the true/false samples were all different. I was considering doing something about that but I guess I forgot. I totally didn't think about wheels at all. I should update that. Thanks. I spent too much time with my mind wandering on the "be creative" part to add things to the Vehicle class and 1 other class. I had trouble thinking of what to add (even though I know that shouldn't have been the tough part of the assignment.)
