I long for the day when we can get vehicles optimized for E85. With the higher compression ratios possible (105+ octane,baby!), they would be more powerful, and fuel efficiency would be improved. But I'm not sure they'd run well (or run at all) with "mere" gasoline then.

It would be nice if they would consider thinking about wanting to try to take some baby steps. Its been pointed out here several times that the equipment that differentiates a flex motor from the gas only version is minimal, and IIRC in the neighborhood of $100. Ideal? No, what is. But as time goes on more and more of the general population of vehicles having this capability would have positive effects--you can use E85 if you have/want to, incentive for producers to increase supply, try to produce more efficiently/cheaper, thus encouraging mftrs to improve their flex fuel offerings, etc.
A turbo motor could go very far towards optimal operation on either gas, ethanol, or any combination of the two by varying boost based on fuel composition.
But GM for one insists on having flex fuel & non flex versions of the same motor, which I don't really get.
