The following car was at fault, let off, suddenly gripped and fucked it.
Lead car cut in tight on purpose to try make the other car slow and fuck up, but fucked up too much and hit him.
Sometimes that can be called as the lead car being just too dangerous, but not that once I doubt.
Either way both cars wrote off so neither would get through to the next round of the event.
Not much room for error at well over 100mph...
