Honestly if it went to $5 a gallon i would still speed everyday, so not like its going to change my driving habits. It wont. Only i can do that. And it wont be anytime soon.
What i think needs to be done is more people really need to take better care of the cars they run. Some people run 30 and 40,000 miles before changing an air filter or run 15k between oil changes. Idiots.
