In the reality of it all, what means more to you, than your life? Using some extra gas, not getting the ultimate mileage, a couple hundred dollars more per year for car insurance, pale when compared to loss of life.
In 1974, I was in a big accident. I was doing nothing wrong. Some 16 year old, stole (of all things) a city sanatation truck, (better known as a Garbage Truck), and was running from the police. He turned down a side street, flying and at the end of the first block there was a STOP sign, which he chose to avoid. It that very moment, I was going across the street that had no STOP sign, but I was going like 25 MPH. I looked to my right, and I saw that I was gonna get clobbered (no worse feeling in the world) and I slmmed on the gas as I though I could get out of his way. No Way. He slammed into me on the side rear quarter panel, sending me into a 360 spin. The car did a 360, came out of it and because of the huge torque from introducing the gas pedal to the carpeting, she shot like a bullit our of the 360 and across the street & into a fire hydrant, immediately severing the hydrant at the entrance of it by the ground, causing a volcano-type erruption of water spray. Then the car went on & into a tree trunk.
The 5,250 pound 4-Door Hdt. Imperial LeBaron was totalled, and had to be removed on a "dolly" (Small trailer with wheels that they get the carcus up & on to.)
Me? I suffered a cut on the left elbow, that was attended to by First Aid Squad at the scene. They aren't making Garbage Trucks smaller, so I don't wanna downsize, either!

Imagine if I was in a small or mid-size car?
