$4.00 gas coming. How to save gas

I have a friend that is also a Real Estate broker.   To save gas all summer he rides his motorcycle. Everyday all day.  He rides it when listing or showing.   He swears to me it does not hurt his buisness at all and that he advertises on  biker sites. He usally sets up an appointment and his customes who ride their bike to met him.  He says it creates  great bond with his buyers and they seldom use any other broker. He is located in a vacation and second home market.  I am not.   Does any one out there also use their bike in the Real estate buisness. I would like to hear youe experience.
