Thanks for the oil reminder. How bad are the original tires?

I have essentially two possible routes to/from work, and (fortunately) neither has any true "highway" (limited access, 65 miles per hour limit). Both have a mix of rural roads with limits between 40 and 55, and light to moderate traffic, and small city streets with lights and moderate traffic. In summer, one route tends to give better FE because it doesn't have the huge up/down, but more gentle, rolling hills, but I haven't been taking that route in winter because (1) I've been more pressed for time, forgetting to allow extra time for clearing snow from the car, and (2) I'm not sure how well it's plowed. I might try it on low-snow days with the Prius.

OK, I know DWL, what's "DWB"? All that comes to mind is "Driving with Booger" (that's my cat, and I don't think it would improve my FE!). And pardon my ignorance again, but "WAI"? (Neither of these are in the glossary, BTW.) (edit: Oh, is it "driving without brakes"?)

I already turn the engine off at long stop lights during warm up - it's almost second nature. Is that what you mean by FAS?

Oh, by the way, I got a good laugh the other day - I was reading a novel where the author is trying to impress us by mentioning one character's Prius repeatedly by name, but he totally screwed up - he wrote something about "turning the key in the ignition" to start it! Obviously has never driven one... heeheehee. Here it is: Michael Crichton, "State of Fear" (Avon Books paperback) p. 164: "Evans turned the ignition of his Prius and it hummed to life." (Could this have been true of a Prius I? Maybe that explains it.)
