What are the track borders for and where do I need to use them?
The borders allow the car on the outside lane to slide out on the turns as much as the cars on the other lanes do without running up against the guard rail or putting a wheel off the track edge; either of these things will usually cause the car to de-slot. You should use borders on the outside of all curved track sections, on the straights before and after each turn for at least two full straight track sections, and on the inside of any turn immediately following a turn in the opposite direction. If you plan to run your track in both directions, make sure you have placed the borders in the appropriate places for both directions of travel. The straight and inside borders allow the cars to get straightened out after a curve without dropping a wheel off the edge of the track.
