EXACTLY! and what happens when we apply some force to the horizontal axis of a spinning wheel....it tries to LEAN OVER. However, in the case of the spinning top, centrifugal force simply pushes in all directions equally, so it has essentially 0 effect on the top's lean. The top is actually constantly trying to fall over, but precession moves the force 90 degrees before it can, and it stays upright, always 'falling' 90 degrees behind the force.

but this is a rolling patch, not constant....if you couldnt change a contact patch's path, no vehicle would turn

It will make your hand move so the axle is horizontal and thus resist you wanting to move the axle or wheels axis around.

Been there done that, back in middle school science class.....see above for how it applies to front wheels

I think we are in agreement on several factors here actually...I just dont think you give the gyroscopic forces enough credit
