Grand National passes Corvette as it wrecks
John N. testing his tricked out Stage 2 Grand National at Thunder Valley Raceway park. His opponent in a Corvette stays in it too long and narrowly misses hitting the GN as it passes by! The GN's build up had recently been completed and this was intended to be a soft pass with only 20# of Boost. The camera person was there to film the car's reaction to the launch for tuning purposes. They were so focused on the GN that they did not notice what was happening to the Corvette until it was over.
