Gas is still too cheap

People whine and whine and whine about high gas prices. But I still see them idling their cars in the drive-through and carwash lineups, and speeding down the highway at gas-guzzling speeds. Eighty to ninety km/h is the ideal speed for minimal gas consumption. All right, so most people don't want to poke along on the highway at 90. But going 120 or 130 will make you rip through a lot more gas than 100. Then there's the guy I saw the other day, SUV parked at the mall, napping with the engine running (so the air conditioner could run, presumably). We're talking April here. The weather was hardly sweltering. If gas is cheap enough for him to foul our air for the sake of his nap, then it's too cheap.
