Assume I drive from age 18-90, and that it takes ten minutes to get gas. That's 144 lost hours, or 3.5 work-weeks wasted getting gas when I didn't really need to. I'd rather take a European vacation instead.

Also the extra start-stop cycles cause engine wear, but that probably only matters if you run your cars until they need an engine overhaul.
