I think that Toyota could easily settle for much more than that amount. The number of hybrids sold last year alone topped the 1/4 million mark from: www.greencarcongress.com/2007/01/sales_of_hybrid.html Toyota sales represented 75% of the total according to the article. The electric wheels cost either 18k or 33k from Solomon. If you figure they have to settle for lost profits, then: (250k)0.75*20k = $3.75 Billion And that is just to cover last years US Toyota hybrid sales. Someone feel free to correct me if I am wrong here.
