Trapdoor for the gas cap
'InStant Fill' uses trapdoor mechanism
As much as we hate to think about gasoline--its ever-rising prices, more specifically--this is an item that could save a good bit of mess at the pump.
Gas caps can be a pain to use, especially if you're as forgetful as we are: We've left a few of them behind by accident, next to the coffee on the roof. But there's an alternative called the "InStant Fill," a device with a "trapdoor mechanism" that allows you to insert the nozzle without removing the cap. Book of Joe notes that it's also an official NASCAR product, so you can time yourself at each pit stop while reliving Talladega Nights.
