Road turntable + Terence turntable help

[Super]

Might the rollers on the turntable that the wheels spin on actually like, wind (tighten) a spring while turning and release when Terrence moves off so it springs back? Could the wheels sort of slip on the roller so the spring isn't wound the right amount of times to spring back? Maybe clean Terence's drive rubber wheels (the rubber should be removable) and the rollers with a cotton swab and a little rubbing alcohol so the traction is better. Also, are the rear tires bald which can happen with a lot of use? Just thinking out loud.
