In an aspect, the invention is directed to a set that includes a miniature vehicle that drives one or more wheels with an on-board motor that draws power from an on-board power source. A switch is provided to control the transmission of power from the power source to the motor. A first drive-related magnetically-responsive member is movable between first and second positions to control whether the switch is off or on. A second drive-related magnetically-responsive member is positionable to interact with the first drive-related magnetically responsive member to move the first drive-related magnetically-responsive member to the second position so as to close the switch.
