Perhaps it is of no surprise to anybody that Sam Hornish, Jr. was the reciepient of the most pit penalties laid down by NASCAR in the 2010 season. Hornish led all of NASCAR's Cup series with 22 penalties, just one more than Brad Keselowski and Marcos Ambrose.
The least penalized driver who ran full-time in the Cup Series in 2010 is:
It's probably a shock to many that Dale Earnhardt, Jr. was the driver who had the fewest pit penalties in 2010. Even though Dave Blaney was a full-time Cup driver and did attempt all 36 points events, most of Blaney's efforts were start-and-park effort which put him at an unfair advantage given that there would be far fewer opportunities for mistakes by he and/or his pit crew throughout the year.
