I don't think copyright laws apply to brand names. I think brand names require registered trademarks for protection.
I think a lot of the name suggestions thus far (excluding mine, of course ) have a comic book quality to them and would be better suited to kids' toys. Step back for a moment and consider whether an adult would be more willing pay many thousands of dollars for a vehicle with a cartoon sounding name. I don't think so.
If you are laughing at your own density, then who am I to stop you? You understood my point whether you choose to admit it or not...right?
