The crashes are, I imagine, down to the laws of physics overcoming the lack of the driver's recognition of them. The fires? Well, it probably just goes to show how far the attention of Italian manufacturers attention to fuel and electrical system integrity and reliability has progressed...or not....
The piccies do show the effects of fire upon carbon fibre and plastic quite well, rather like the days of yore with the early Reliant Scimitars, which caught fire because the fuel hose connection to the carb was not pinned and worked loose to spray fuel all over the nice hot engine and exhausts. I seem to recall that the result was much the same - a few metal bits left at the end...
