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.

Doesn't necessarily follow. Studded tires come to mind.


But depending on weight distribultion, and assuming the studded tires
dont simply carve a big hole in the road surface, all that that might achieve
might be to send the front of the car into the air, if not flip it over
completely.


Front wheel drive.

And overal studded tires would be a specal case dependent on an
optimum road surface, and optimum weigh distribution and would only
be applicable up to a certain speed.


All cases are special cases and depend on all the factors you mention.


What was being proposed, was a general principle.

If all cases were special cases, then there would be little point in formulating
general principles at all, would there ?
