Good to know: no time travel.

If you're worried about it passing inspection, why don't you just travel to the future and see if the inspectors will clear it?
Hmm, actually, if you're already in the future, you may as well see who wins nationals and see if it is worth it to keep working (yeah, right - like anyone's going to pass up building a robot). Then again, if you are skilled enough to build a time machine, then beating Overdrive should be a piece of cake.
One piece of advice - make sure that if you go to the past, be sure to have a backup in case you go to a time before Exide batteries were invented (otherwise you'll have to go through the business of stealing a train and all that business).
