Yep, it's just the decrease of vertical distance that
gives the mass less time to accelerate.

The precession force is present as long as the wheels are turning,
independent whether they turn at the speed of the asphalt or not
(= slide/skid). So if you would literally "lock up" the wheels,
this resisting force would not be present.
