I swear people must be stupid.

On one day you will have them bitching sulfuriously about the price of gas. The commentary will be that high gas prices are the ruination of society. We will be completely bankrupt by ruthless corporations bent solely on stealing our hard earned money.

Then another day when its only modestly cold, they will start their vehicle 15 minutes before they intend to go home so that the interior can be warm when they get in.
