Car Wash
 

Here ya go, how about one of those car wash tracks? Pop into N, shut 'r down and get jerked along by an electric motor :p

How about a mandatory tax for using the DT as a function to reduce usage, and use the money to research/promote fuel efficiency? Some states have different tax structures for eating-in at a fast food place versus using the drive-thru (but it's usually tax inside, only drinks taxed in the drive -- reversed structure). Yeah, that'll happen :(
