No actually I'd say you are missing the point...

Since you could do all the commuting with a pure EV... Why put very expensive and highly inefficient hybrid parts in a car and then call it "more" environmental than the next car when in fact that can be highly questioned...

The argument here is also a bit silly... No, none of the many energy conversions in the chain in the hybrid is 100% efficient... Most are well below 50% efficient, so in comparasion to a ICE using top notch technology it's highly inefficient...

Old Mech... You seem to be agruing that a ICE coupled with a hydraulic transmission system (what you call a hydraulic Hybrid, with "motors" in the wheels) is more efficient than an EV?

Again... That is stupid... You are comparing apples and oranges... Of course a hydraulic transmission beats a mechanical, every day...
But calling that a Hydraulic Hybrid is just stupid... There are no hydralic motors there as far as I can figure... The hydraulic transfer the energy from the engine to the wheel, same as the mechanical parts do on any other car...

Now the hydraulic system is very efficient, but also expensive... If you couple it with a good ICE, you get a highly efficient ICE car... Not a hybrid... If you instead drop in an electric motor, you get an insanely efficient EV, since the electric engine is much more efficient than any ICE engine... Now bear in mind my wording... I'm talking energy in in one end, to the shaft out of the engine, not well-to wheel... well-to-engine out if you will...

Then stick on the hydraulics and the well-to-wheel number gets really good...
