Why is the Pinewood derby rigged?

What makes you think that it is rigged? If you have the same people win your Pinewood Derby over and over, it is most likely because they are putting more efforts into their cars. When this begins to happen at a Pack, the Pack needs to offer workshops that can raise the bar, so that all racers can compete fairly at the elevated level. If the Pack doesn't do anything, people will lose interest in competing in the derby and before you know it, only the winners will be the ones showing up to race. This scenario has killed many good Pinewood Derbies in scouting. It is not enough now-a-days for a Pack to hand out kits and say "see you all on race day!" Packs must offer a competitive program that allow racers to build competitive cars. It is the Pack that is letting down it's members when failing to create a fair enviroment.
