Yeah, unless you make a consciencious effot to use less gas, what effect does it really have? Just means twice as many people will buy gas the next day. If you really want to make an impact convince people to have one driving free day a week (obvioulsy everyone can't do this, but some people could if they made the effort) type of thing where they don't drive at all, or have people do things like stop at grocery stores on their way home from work rather than going home than going to the store later type of thing.
