I, for one, am unsatisfied with the off-the-line performance. When I pull up to a Tesla P85D (eventually), I don't think I'll win. 
I didn't buy my FFE to win races or anything; however, shortly after owning it, I realized how fun it is. Although 0 to 60 in 10 seconds isn't anything other cars can't do, with an FFE, you can do it ever-so-quietly...which throws many people off. Although we have to "floor" it, it comes without guilt of wasting fuel, excessive noise, or wear and tear on the vehicle. Well, I'm sure I'd be wasting fuel, but wrt an ICE, I'm not. And, there may be some extra wear and tear on the battery and some of the electrical components, but hey, if they don't wear out before the 96mo 100,000mi warranty expires, they'll probably keep on working...and if they don't, I get new ones; an besides, on the MFM website, I'm much closer to zen than zippy.
I do believe that Ford likely limits the throttle a bit. With the econo tires, the wheels would break free of the pavement if they didn't throttle it. Even today, the streets were wet from early morning rain...and giving it full throttle at 30MHP, my wheels broke free. Although it would be cool to have control of the limits, without them, I think we'd be all over the place...and in less time
