I like the DD4H and 5Kids collaborative efforts and ideas. More opportunities for others builders to get into the winners circle, rather than just the multi-car builders sweeping all the top spots. Gives the little guy a chance.
Another thing that I would like to see is a Rookie of the year award. I am not sure how this would work though. Would you keep track of it by awarding points for racing in an event, qualifying for the finals, points for finish, bonus points for finishing in the top X, and so on. Of course, you don't want it over complicated and what I mentioned are only ideas of what could possibly be done. Let the brainstorming begin.
