gas-o-meter

An old mate of mine with an old Valiant had a guage in his car that would tell the driving habits of the driver, with the guage reading "economy" to "poor", depending on how lead-footed one was driving. It was a very simple guage connected up to the engine and I could see just how lightly one had to use the accelerator in order to get good fuel economy out of the auto.
this is one simple step that anyone can take without gadgets.

driving slowly

I was driving slowly across the Story Bridge the other day only to get beeped by a council bus coming up behind me. What is it with these guys in big buses that give them an injection of testosterone. The good thing about driving slowly is of course you don't use as much fuel and it's just more fun( I think).
