I was setting on my trike outside a dealership. 3 riders pulled up and parked along side of me. They exited their bikes and were standing outside the entrance door. I happened to take notice to one of the rider's bike seats. In one spot of the seat. A pin hole sized spot on their seat started to smoke. I called to one of the riders and said your seat is starting to smoke! He rushed over and sure enough. In one little spot it was starting to burn and melt! He immediately started taking his seat off, which ceased the burn that was taking place. What had happened. Is that when they pulled up and the way they were parked. The sun was reflected from one mirror to another's mirror and then to his mirror and then to the seat. It acted just like when one uses the sun through a magnifying glass to pin point the intensity of the sun's ray. Luckily I was there to notice this. It would have been a real bummer to come out to a bike fire! And to never know how it ignited.
