Well, with my commute (50 miles round trip) and flat IL (no mountains) I have never seen EMM, FMM, or really needed Mountain Mode. But I could see someone who is clueless about cars might freak out when EMM or FMM pops up on the dash. With my own experience, I saw picture of the concept car, really wanted one, saw the first year MSRP in Nov 2010 (started at what, $41K?) and brushed it aside as "no way am I paying double for a PHEV." In Feb 2013, the local car dealership had a few on their lot, but they were premium models at $44K. Again I though "no way this has any ROI whatsoever... I'll let the people who want to be green pay to be green". Then in Aug 2013 the $5K price cut came. A coworker bought a Ford Fusion Energi, but mentioned she really liked the Volt, just couldn't wait a few weeks for one as her previous car was on its last legs. A week later I found out from my brother in law that IL had a $4K rebate on EVs. A quick call to the dealership, all the national, regional, and local deals stacked up with $4 per gallon fuel and a gas guzzler of a Deville, the planets aligned and I bought a Volt with sales tax for $23K below MSRP. Yes, I geeked out and read the entire owners manual and fiddled with all the gadgets, but I'm a computer scientist by education and profession. But to GM's credit my wife just jumps in the car and drives it. It took a bit for her to figure out the climate controls, and even today, she refuses to just hit the Auto button - she has her own pattern of turning up the fan, switching to the window defrost vents so it doesn't blow in her face, turning off recirculation - because that's the way she likes it). I don't think she has ever pressed the Mode button.
