Nearly had a fire

Just had this unusual experience.
Opened the bonnet of a 412, and soon afterwards there was smoke. Coming from a piece of carpet.
At first i was confused, as the battery was disconnected at the time. Then saw the upside down chromed hub cap lying there. It was concentrating the hot sun rays onto the carpet, like a magnifying glass.
Seems the 412 hub cap has a near perfect parabolic dish shape. (Except for the part with the VW logo).
Cleaned inside of the hub cap and tried concentrating the sun's rays onto a piece of newspaper. Newspaper was burning within seconds. Wonder how many fires started this way, and people afterwards never realized what the cause was?
