I don't see the big deal about "LIVE". I don't see how it will bring new viewers. If anything it will have the opposite effect. The diehard fan is gonna watch no mater what.
We understand the cool down, turn around time. BUT The casual channel surfer that we are trying to hook, when we tunes in to see racing, that's what he wants to see. Not how many miles JF puts on his scooter in a weekend and all the other fill in stuff. If he sees racing on the guide, and tunes in it won't take much fill in fluff to make him grab the remote again.
