John McCain and his GOP surrogates have been having a grand old time making fun of the idea that people can help reduce dependence on oil by properly inflating their tires and keeping their cars in tune.  

If everyone did this we'd reduce our oil consumption by 3% to 4%,  freeing an amount of oil greater than any could be found by drilling offshore (or anywhere else, for that matter).  Moreover, that 3% to 4% savings will happen immediately, not in 7 to 10 years, and is there for the taking, unlike oil that may or may not be in the ground.  

No environmental risks, no expensive "dry holes", no 10 year wait for results.  Yeah, that's funny.
