With $2 Gas, the Toyota Prius Is for Drivers Who Stink at Math

There’s a big discount on driving these days, thanks to the drill-baby-drill refrain at OPEC that's echoed in Texas and North Dakota. The savings are most concentrated for those driving cars with old-fashioned combustion engines. A road trip in a Ford F-150 pickup from New York to Los Angeles costs about $292 at the moment, roughly $84 less than it did just two years ago. A stop for gas in the middle of the country will cost less than $2 per gallon.
