Probably makes sense.
I typically drive stoplight to stoplight in heavy traffic and my civic coasts almost too well, so I typically begin braking very early.
I'm mostly just bad at pulse and glide in the city (I still think I'm better than 95% of the the other idiots on the road). Maybe a 3rd switch to sense moderate-hard acceleration or braking?
Also, I believe at least one manufacture (Mazda) is doing something similar - disconnecting the alternator at cruise, and using the alt. to charge a capacitor when braking.
