If soaring gas prices are hitting your wallet, the most obvious way to cut back on the expense is to reduce the amount of driving you do and the size of the car that you drive.
But one overlooked technique is to slow down. According to CNNMoney, "In a typical family sedan, every 10 miles per hour you drive over 60 is like the price of gasoline going up about 54 cents a gallon. That figure will be even higher for less fuel-efficient vehicles that go fewer miles on a gallon to start with."
If you care about the physics of this, read the article. This seems like a pretty good win-win: drive safer and save money. In addition, keeping your speed down will reduce your chances of getting traffic violations which drive up car insurance premiums.
In other driving news, if you're looking to slow down your speed demon teenage son (or daughter, but most likely son...), you might want to look into the Drivecam. A recent Wall Street Journal piece spotlighted how this device can monitor your teen's driving, sending you a weekly report of how safe junior is.
If you're paying for his gas, which I hope you aren't, tell him to slow down and stop wasting your money.
