I have been recently cognizant of my driving habits due to the high price of gasoline. I'm no hyper-mileager; however, I generally think and plan while behind the wheel. There are some pretty serious inclines between BCIT and home. I shake my head as I see most cars fly up the hills with their right feet buried in their carburetors. It's doubly silly as, although they blast past, we again sit side-by-side at the traffic light further up the road. They ended up sucking up far too much precious fuel for absolutely no measurable advantage.
On my first car, a Ford Pinto, I put in an extra gauge that measured the manifold vacuum pressure. I don't know why other than perhaps it was fun to watch. By driving as if the accelerator were a fragile egg, I could keep the gauge firmly in the green, fuel-saving area. Getting a run for hills became second nature. It was perhaps physics class where I figured out having to use the brakes meant one was wasting momentum that one had already paid for in spent fuel. Looking a bit beyond the hood is a good practice. There's no reason not to coast up to a traffic light that's going to be red.
Driving to save gas means driving safely as one is more aware of the highway conditions. It's a shame that more people don't bring along their brains when they drive somewhere.
