The actual grid and battery turnaround efficiency and motor efficiency
will be somewhere in the 80%-90% level

Couple that with a 60% CCGT power statin and you have around 50%
gas-to-wheel which is better than any IC engine will achieve.

Add in some regen braking and you could be up to 50% more fuel efficient.

Especially considering you can do a better job optimising leccy motors for
low power cruising.

You got that pretty well spot on. Look at my post on fracked gas in the UK
and small unmanned local gas powered power stations - these can be small
unobtrusive buildings nestling in the districts. These are some now in
cities to assist at peaks with gas turbines in them. Then the efficiency
goes way up. And the pollution levels drop like a stone as local homes are
heated by the waste heat (as in Sweden) and only EVs and electric trains and
trams are used.

We have no choice but to start the ball rolling to this approach - that is
if the country is going to use this gas in a big constructive way.
