It seems you are Dave Plowman, and I claim my £5

Engine RPM is not directly and irrevocably poroprtional to road speed

WE have a gearbox.


Yes, and in every gear the engine RPM is directly and irrevocably proportional
to road speed.

The speed/time graphs are exactly the same shape in every gear. Acceleration is greatest at the
highest TORQUE regardless of which gear is selected.
