Of course you're assuming that the "gas light" will always come on when there's the same amount of fuel left. Not exactly a safe assumption, at least with any car I've owned. While the Insight's pretty good, my pickup's gauge can vary by about 1/4 tank depending on whether I'm headed uphill or downhill, and the Miata can go about 250 miles on half a tank, and maybe 150 at most on the other half.
