One speed/one load genset for electric vehicles 3

[icelander]

The general direction of combustion engine development is towards increased complexity to retain efficiency over a wider range of speed and load, with Daimlers DiesOtto as possibly the pinnacle. Going the other way, designing a combustion engine for one speed and one load would shed loads of compromise and complexity. Flow simulation now makes "easy" optimizing such an engine (presumably 2 stroke, valveless, minimum peripherals, cheap to produce) to the maximum efficiency/emissions point. A similarly simple and optimized single load/single speed (on-off) electrical generator would absorb the mechanical force, batteries serving as load buffers in vehicular applications. Since no major players seem to follow such a strategy the question is simple.
Why not?

I saw a rather neat proposal for an electric guide rail system, so you used your own battery for maneuvering, and then on the freeway you picked up the rail and it supplied you, guided you, and controlled your speed, and maybe charged the battery.
