Completely disagree. I find F1 guests far more interesting than the regular guests who I have no interest in their lives or have never heard of. The Prescott interview was good, but generally SIARPC is often the low point of the show for me, unless they have an F1 guest on and then it's interesting. Otherwise *yawn*.F1 people are boring. They can drive fast, but the rest of their appearance will put everyone to sleep. The less F1 drivers they have, the better. With the possible excption of Gerhard Berger. It may be fun to hear how he flooded Senna's hotel room and similar prank stories.
For years I've wanted to see James Hetfield as a SIARPC, but I guess that's in TGUS territory now.
