Self-Syncronizing Lift Hills or Path Points

Sometimes in a ride, multiple ride vehicles need to be synchronized so they all are at the same point at the ride at the same time. This feature would allow you to define points along a ride path where the vehicles would always "meet up."

For dark rides, this would allow sets of ride vehicles to all move from one room to the next at the same time, or one vehicle wait until the next vehicle has joined it. (Think Pooh's Honey Hunt or the PeopleMover)

For coasters, this could allow a self-syncronizing lift hill, so dueling coasters could exit the lifts at the same time, even if they didn't start the lift at the same time. (Think Dueling Dragons)
