And the fact remains that - at any given speed - the highest instantaneous rate of
change in speed (acceleration) is obtained by maximising the amount of power
transmitted to the wheels. Simple laws of Physics!

Surely maximising the amount of power transmitted to the wheels
to change the speed from say 1 mph to say 5mph would simply
result in wheelspin. As many boy racers at traffic lights know
to their cost, never mind many stars in reasonably prices cars*.
And the same would presumably also apply in wet or icy conditions*
at much higher speeds

Not that the same doesn't apply equally well to torque.

Well yes, of course. But I think we're assuming we have a dry road with
plenty of adhesion.

[I did in fact cite icy conditions at one point when trying to explain
to My Plowman what I meant by "thrust"].
