That would work, but I would have to depend on my kids to set the clamp
when they get off and hope they remember to unset it when they get on.
I would be afraid that it would get set open and not thought about, or
even worse, locked at the bottom (brake on) and someone at top hits the
recall button and has the cart connection point ripped out.  Or on the
opposite situation where its locked at the top and the cart is called
down and the cable unspools up top.
