I'm curious about the following. The question was asked earlier if you would move towards a 100% implementation of one fuel supply. You said you did not want to put all your eggs in one basket. It wasn't all that long ago that gasoline was the only option that we had—and that was all our eggs in one basket.
My question to you, though, is this. If this fuel source works so well for the vehicles where you have made the conversion, why wouldn't you do that?
