You are setting up an impossible tautology.
Say that the side walk senses how fast the wheels are moving and then matches that speed. Let's say at instant 1 the sidewalk has zero velocity and the tow rope has a velocity of +5.
instant = 0; tow rope velocity = 5; wheel velocity = 5; sidewalk = 0
instant = 1; tow rope velocity = 5; side walk velocity = 5; what is the wheel velocity? 10!
So instant =2 tow rope velocity =5 sidewalk velocity =10; wheel velocity = 15 etc.
The wheels will always be spinning faster than the side walk because the speed of the tow rope is externally setting the speed of the person.
