Did NASCAR Ban Drivers from Driving in BOTH the Indy 500 and the Coca Cola 600 on the same day?

May be...

They moved the time of Indy.. They can still do it, but the threat of rain can delay the Indy race, and make the whole thing impossible..

No, but weather and starting in the back due to missing the driver meeting are two reasons drivers don't do double duty any more. If the 500 gets slowed by rain, then the driver doesn't get to finish and leaves his chance to win up to a relief driver. Robby Gordon, when he had to start in the back, crashed a couple times really early in the race, so he doesn't do it anymore. Also, the qualifying and practice days take up Nascar time.

A lot of people think one of the series did something to prevent it. I think that is due to a few years ago there was a conflict with I think Stewart. He wanted to run the Indy but there was a manufacturer conflict with the car he could have drove at Indy. He decided not to run that year. After that, not related, the IRL decided to make it a later start time making it very difficult for a driver to pull it off and not really worth the reward to try and pull it off.

no, the IRL just moved the start time of the indy 500 up from noon to 1PM, so now the logistics make it impossible for someone to run both

well, i'm sure they could do it, but how would you expect the driver to get from one venue to the other. i doubt the driver could finish the indy, then fly to north carolina and do that race.

but more importantly...... how can a driver drive in NASCAR and INDY?

nope they just moved the time to where they can"t do that anymoregangsta race ppc
