[Zerahan]

Most of this is unnecessary for the MVP, but designing the game with these in mind should make integrating these features easier down the line.

• [ ] Points of interest are always in the positive X direction from the origin.
• [ ] The travel map is in the negative x direction from the origin
• [ ] Once the truck moves to a certain location within the travel map, it slows to a stop as the world under it starts moving.
• [ ] Points of interest have a shell that is loaded into the travel map so you can see the POI coming up down the road. Or growing distant from you.
