Bingley - there was a really nasty accident a while back - in CA I think. the person had a couple of plastic jerry cans filled with gas in the back of their car. Not the trunk - it was actually in the back compartment of a wagon. Static electricity ignited the gasoline fumes - which erupted into a fireball INSIDE the vehicle. The driver was killed because of severe burns plus the inhalation of burning vapors into their lungs. It's very nasty.

always carry gas outside the compartment of your vehicle, and best in a metal jerry can that can be grounded.
