Good question.
It looked like he was driving to his stall and Robbie just plowed into him.
Yep. Apparently, it was in retaliation for something Dale did to him during the race.
It all started when "little e" began putting rubber "doughnuts" on Robby's racer after the race was concluded.
It looks to me like "badpuppy" has an axe to grind with DALE EARNHARDT JR., judging by your slurs in the title and the above post.
JONATHON & STEVE :
So you know the "rest of the story" -- Earnhardt Jr. was leading the race but chose to pit and get 4 fresh tires during a late caution. As a result he fell to 10th place. After the restart he flew through the field, passing 6 cars in 5 laps. Gordon was a Lap down and out of contention, but when Earnhardt Jr. got to him he became, in JR's words, "A moving Chicane".
Basically he BLOCKED Earnhardt Jr. and as a result Jr. finished 4th when he had a realistic chance at getting 2nd or 3rd and maybe even catching the leader.
After the checkers he pulled alongside Gordon - ON THE TRACK, AWAY FROM EVERYBODY, and "donuted" Gordon's door. Which is basically a meanouver where you rub the side of your car against the other, Leaving a "Donut" imprint of your tire on their car. Watch the end of any NASCAR race and you will see "Donuts" on the sides of about 50% of the cars.
Gordon then got behind E, and as they entered pit road - FILLED WITH CARS, CREWMEMBERS, OFFICIALS, and MEDIA - and slammed the rear of Earnhardt's car. Sending him Spinning out of control down a crowded pit road.
Since GORDON's actions ENDANGERED people, he was hit with the higher fine.
The HARVICK incident happened quite a bit differwntly. Greg Biffle Spun Harvick during the race, causing him to slam the wall, and put his car out of the race.
Harvick then waited on top of his pit box until the race ended. When biffle pulled into the pits, Harvick ran down pit road, jumped the wall, basically dragged Biffle from his car and started shouting in his face (I am sure they were just making dinner plans).
