You push a button and soapy water sprays all over your car from a spout on the roof, followed by a warm rinse (somehow warmed by the heat of the engine), then your whole car surface heats up a little to dry itself. instant carwash.-- aquamarine, Oct 17 2003 been there, done that. sorry. http://www.halfbake.../idea/mobile_20dick [po, Oct 04 2004] Has the added benefit of deterring tailgaters.-- 2 fries shy of a happy meal, Oct 17 2003 I still think you'd need to step outside the car with a sponge and go over the car to get rid of the road grime. Merely spraying the car with soap and water won't wash it.-- Cedar Park, Oct 17 2003 suggest you do a little searching before posting. this category (other:general ) never reveals very much.-- po, Oct 17 2003 believe it or not i searched for at least a half hour, but i was looking under cars and there were a lot! i would think a half hour qualifies as a little searching. somehow i didn't think to look under mobile dicks.-- aquamarine, Oct 17 2003 hmmm, yes - sorry about that! welcome to hb [aquamarine]-- po, Oct 17 2003 Wow! Wow! Not only is this hilarious but [po] got to it first!-- phoenix, Oct 17 2003 random, halfbakery
