I assume you're going for an abstract variant of "Automobile"
I'm not so happy ..."Automobar" is a struggle for me. If you had "Automobel" ...as an abstract word, I'd possibly give it a pass. Little value, in my little opinion (sorry)
Mmm, I like the inspiration ...maybe, just don't think I'm convinced, need to capture someone's imagination with that ...very specific (hope I'm wrong)
