i had to laugh at this on the F1 site
"The team have also confirmed that their race driver line-up for the 2009 season will combine the talents of two of Formula One's most experienced drivers in Jenson Button and Rubens Barrichello. The race-winning drivers continue their partnership at the team for a fourth consecutive year, forming the most experienced driver partnership on the grid with 423 Grand Prix starts between them."
most experienced at being at the back?
