Will hybrids sell?

Mark Phelan at the Detroit Free Press asks whether the will hybrids sell? Not an entirely wrong question, I should say. However, I still believe that Detroit can't get hybrids on the road because they DON'T KNOW how to make them, not because they are afraid of the market conditions. I may be wrong because the truth with Hydbrids is that you need to produce them in mass to bring the costs down for the majority of the market to buy them, otherwise Hybrids will just be reduced to a niche that they are currently. Now, Toyota thinks that the way to go forward is to hybridize the entire line of their products and sell them as vehicles which save fuel and hence are better for the environment. Which approach do you think is correct: The one taken by Detroit or the one taken by Toyota??
