Wow! I never thought about looking at how much I've spent on fuel over a long period of time. The problem for me is that we have multiple cars.

I currently drive until the red light comes on, fill up, and look at the trip counter to see how many miles I've driven since my last fill-up. I then reset the trip counter and repeat. My time is spent in mixed highway and city traffic.

I'll have to look at modern hybrids once something actually breaks on my car. I'll consider everything equally once it's time to shop again.
