Also, Fernando and Jimmy Johnson swapped rides on Monday-

This was a 2013 McLaren, not the most recent one. But Johnson was able to get within 0.2 sec of Fernando's benchmark time set in the car. Which is just like the last two times that a cup drive swapped seats with an F1 driver- where the cup driver was much faster than anyone expected in the car- and much faster, relative, than the F1 driver was in the cup car. I really don't like watching NASCAR, but I certainly appreciate how good of drivers they are- I've done a NASCAR drive at MIS, and they balance a heavy car, with little aero, on small tires for hours at a time. Pretty amazing.
