To be fair to Fringe they built a 9 wheeled buggy and a conventional 3 wheeled buggy, the latter of which ran pretty decently on Raceday.
The 9 wheeled buggy was more of a fun side project is what I've been hearing.
I however, do agree that when teams are approaching records it is better. The issue with saying as long as teams are competitive between themselves and having fun it's fine is BS in my opinion because Buggy, unlike most sports, is still heavily technology reliant. The United States (or Jamaican) olympic sprinters couldn't win with some of the 4 wheeled buggies+wheels from the 50s against the top buggies+wheels today. While the athleticism of the top push teams can vary year to year, we expect that the fastest buggies won't be getting slower.
So when teams are rolling 2:12s to 2:14s on buggies which have, just a few years ago, finished at 2:03 to 2:05, it's concerning to me. I'd chalk up 3-4 seconds to the road conditions on the back hills and the chute, but make no mistake, the top push talent just isn't there right now.
