Every morning, before work begins, there will be a three-lap forklift race around the Harbour between Ryo and four other forklift operators. Your opponents don't pose all that much of a threat, but the route itself, which is always the same, can be tricky, especially where objects in the environment are concerned. Be especially careful when turning corners as the forklifts have a tendency to 'stick' if you are too close to the object you are turning towards.
Here is a video of the race :
