Read at Jayski and heard on Rowdy.com that Nascar will be changing some pit road rules. This one caught my eye:

Another change this year is if a car is entering pit road or just entered pit road when the caution comes out (thus closing pit road), the driver can go down pit road (without stopping in his stall) while maintaining pit road speed and NASCAR will put the driver back in his spot when he entered pit road. There have been times guys entered pit road just as it closed because of a caution and never had a chance to react and all but had their day (or a good part of it) ruined with losing a lap.

So the day after Robby announces the possibility that he will might miss some cup races, Nascar comes out and gets rid of the "Robby caution."
