My stratus follows energy content & MPG almost perfectly. I don't know if there's a fuel sensor, I don't think there is and it doesn't matter, the O2 sensor does everything that needs to be done as long as they sized the fuel pump and injectors large enough to take full load with E85.
We have liquid fuels and will for a long long time.
Field corn is hardly used for people food, unless you count animals turning it into meat & tasty fat the last month of their life.

Regarding FFV, I am speaking from daily experience. I own a 2005 Tahoe with 5300 flex engine. While the motor runs fine on blends, it is not as efficient. As far as BTUs, experiencing a 10-20% loss of MPG on E10, I would imagine an even greater loss as the ethanol content goes up.
In regards to "Field Corn" no one is making assumption that the corn could be eaten. The fact is that agriculture in general is downsizing each year, and if the ag resource is diverted to fuel production than that leaves far less for food (more specifically grain) production. This is a large reason for the rapidly increasing import of food product. The ag resource is a limited one, and an increase in one area will generate a decrease in another. The impact we've seen from ethanol production is only the cracking of the door.....at this point, ethanol has reduced our gasoline use by a grand total of 7%. At what price?
We have adequate oil reserves to carry us through to a viable replacement, but IMO ethanol, the ethanol coalition and its mandated use is merely a scheme to take advantage of the "green" mindset, and will do nothing more than delay a realistic long-term solution to our energy use.
