it doesn't look like too much fun. You should make your next Racetrack wider for more speed and fun. Plus, don't add all of the extra obsticles that would slow you down.
Looks fun, but again, honor rules are always bad. Nothing good comes out of them. A simple solution would be to make the VIP point high up, and have the players get there by ramp... It would work much better, and you could only go one way.
