Not really, I made sure it was not accident.
I know sometimes you can hit without damage, but You repaired car when it was already on fire.
Someone reported You in some SK race earlier, where in middle of race You repaired car... so I loaded few superhardcore races. Took a while coz in some races You were careful enough to avoid crashing, but finally found Your car was on fire and suddently fire was gone. That was enough to make sure some cheats/mods were used.
