I've seen it done, in fact some HRW members may remember a gathering years back that had all the cars decorated with huge wood screws and saw blades for the demolition derby.
Beyond 3 lanes, it gets problematic. The wiring is easy to figure out because the cars will coast across the gap easily, its the intersection of the slots that require some tinkering. The usual way to make it work smoothly is to narrow the proximal slot and open the distal one, so that the guide is aimed right as it starts to cross the gap, and has the best chance to be caught on the other side of the gap. It doesn't seem to matter whether the crossing is a 90 degree or an acute angle, so you can make it anything you want to fit the space you are in.
