1. Enter the editor and place an AI controlled boat.
2. Give the driver a move waypoint some distance away; just enough to get up to speed.
3. In the waypoint options, give it a timeout time of 30 sec. in all fields.
4. Set a second waypoint after the first.
5. When the boat reaches the first waypoint where it is to wait 30 sec., it will instead oscillate back and forth over the waypoint for 30 sec. trying to stop, after which it will continue on to the second waypoint.
