Here's a silly question.....

Has anyone ever heard of those lenses causing a fire or damaging the interior
by focusing the sun's rays onto a small area?  I've seen people use those
fresnel lenses to burn ants or cook stuff, and wondered if my cargo area
might spontaneously combust.  I can just imagine......

....Driving home from filling the gas can for my lawnmower, the can sitting
in the back of the van, driving along on a sunny day......BOOM!
