And gas man Andrew Rueger was also fined $5,000 and put on probation for the same amount of time as Gibson for failing to comply with instructions from the NASCAR officials during the incident. However, NASCAR said this was not for sending their official tumbling during the incident, which they had decided was just an accidental stumble.
"He might have tripped and stumbled with a shove from another crew member or whatnot," was the view of Busch's crew chief Nick Harrison.
The hefty fine and probation for Busch caught many pundits by surprise, as NASCAR usually takes a "Boys, have at it" approach to incidents during the race; if an action is considered beyond the pale then it's usually dealt with immediately during the race by a penalty of black flag.
Instead, it seems that Busch's previous notorious conduct led NASCAR to decide that his minor collision post-race with Newman was most definitely intentional and then to retroactively roll in the pit lane burnout into their deliberations before handing Busch his fine and probation, even though the driver himself was not directly involved in the subsequent pushing and shoving between the crews.
Last year, the Southern 500 saw an altercation between drivers Kyle Busch and Kevin Harvick out on track that ended up with Harvick trying to punch Busch through the window of the #18 on pit road. That sparked a season-long feud between Kyle Busch and the whole Richard Childress Racing stable.
