Sirius Satellite Radio is allowing NASCAR fans to determine which driver-to-pit crew communications they want to hear each week.
The feature, called "Fan's Choice" will air on one of Sirius' 10 channels that carry driver-to-pit crew communications, but it's the fans that will be able to vote on which driver they want to hear.
Before NASCAR NEXTEL Cup Series race, fans can log on to vote for their favorite driver. The driver with the most votes, gets to be aired on Sirius "Fan's Choice" channel - Sirius channel 140.
A lineup of drivers and their associated channel will be available at sirius.com/driverfeeds before each race.

Watching the race AND having in-car radio is the best.
Thats kinda cool
