I'm definitely Position #1. People will buy what they want to buy, so why not give them the option of getting better MPG in a vehicle that suits their needs? You reduce gasoline consumption a lot more that way.

Hate to tell you this, but most people don't want little cars. They want something thay meets their perceived missions and if it gets better MPG, then they are sold.

I think all the development work needs to be SUVs, crossovers, and minivans. Those vehicles operate in the urban/suburban stop-and-go environment and that is where regenerative braking really shines.

Keep in mind that hypermilers are far outnumbered by people who want to text while they are driving. You cannot change people. Change their tools.
