The end result is the same, the car was a total loss. It is a great road for twisting, but it must be respected, it can bite you in different ways. The video demonstrates that. The driver pulled over for whatever reason and left the car and the heat from the catalytic converter most likely ignited the leaves. Still it is a great road for driving, we run it several times area.
And, this time of year there is a butt load of leaves on and around the road. When I returned from the Back of the Dragon last week I needed a leaf blower to clean the accumulated foliage out of my various grills and from the space between the splitter and the lower lip of the "Guppy" mouth..
I noticed my early morning typo in my earlier post it should have read we run it several times a year, not area. And, in the fall the leaves are an issue on the road itself if it has been windy and raining.
