How retarted. This is the stupidest idea that I've heard of for a few weeks. It's not new either. Other people agree with me.
How about instead of proposing ideas like, "not driving", or "not buying gas" we start driving more conservatively? Wouldn't it make sense to not drive when you have to, when you are driving to keep a lower speed, or not accelerating quickly to the red light 500 yards in front of you? How about filling up your tires or not letting your car warm up?
Nah, that's actually proven to lower consumption, and thereby would lower the costs of fuel. That'd make too much sense, and there wouldn't need to be a "world campaign" to not drive on a certain day. What about those lonely people that don't have a cause to fight about? Think about them!
