Abstract
A toy includes a toy vehicle and a closed loop trackset for guiding the toy vehicle about the track loop. The trackset further includes a booster having one or more rotating disks positioned to grip the toy vehicle and accelerate the vehicle. The toy vehicle supports a momentum sensitive switch and a microprocessor counter and liquid crystal display for responding to each disturbance of the momentum switch to increment the display lap count upon the liquid crystal display. The momentum switch is positioned and configured to respond to the momentum changes imparted to the toy vehicle as the booster accelerates the toy vehicle.
