Hi Bob,
You're absolutely correct.
The faster one moves through the air, the more the air wants to return to the same spot it occupied before it was disturbed.
And the faster you go, the quicker the air is split also increases the local pressure, and this extra pressure moves the air towards it's original position with a higher degree of force.
This force/speed relationship is roughly "linear" for lower Mach numbers and speeds of less than 200 mph or so.
