So we said, "The way we're going to judge this book is to see how people feel one year after it's published," and it was amazing one year after it was published. All these people who were banging their fists on the table came back and said, "You know, this is really important. You really did a good job. I was upset at the time, but now that I see what this represents, I feel very, very differently about it." In fact, we had never planned a follow-on study, and the people came back and they said, "You know, in "The Future of the Automobile" you're suggesting that maybe there's a different way to think about making things. By God, if you think that's the case, you really should continue. You've also set up a very unique process here" -- and we haven't talked about that. Part of the program involved a series of policy forums working with executives from companies and government officials to discuss some of the policy implications and broader implications of the research. So, in terms of how people feel about this book, the book is out two weeks at this point and I think we have to wait at least six months to one year to see and evaluate how people really think.
