update - I have decided to bump up to the car logo level.  I haven't seen much interest here w.r.t. donating to the cause to put the BYOAC logo on a car, and motivation is low with trying to coordinate such things, so I think I'll just put my own company logo on it.  My concern is that all it takes is, say, $1 donated to the cause, and I'm on the hook to change from my own logo to BYOAC - which is already featured on a billboard.  Maybe I'm selfish (ok, yes, i am).  Hope you all understand.  At this point, the 15k stretch goal, to increase content, is almost met, and I've done all I can at this point to help with that.  Looking forward to finished product.
cheers
