Nine of the twelve ideas will save ZERO gas whatsoever. Will i use less gas if I fill up at a service station away from the highway? Ridiculous.

I would almost be willing to bet the IP they are using traces back to China or Taiwan.
Take #12 for example... Participate in a car-sharing plan??? Don't they mean join a carpool?
