Amusing as it may be ... it's really a problem. Many EP cars were trashed at the Kota Raja track and this had deterred some EP Rcers to play there.
One solution could be EP an GP Rcers take turns to run their cars. After all EP cars would barely last 8 minutes per run. Perhaps the EP and GP racers should come to an understanding on this when there are say 3 or more EP cars at the track. Let the EP Racers run peacefully without any fear of being trashed by a 1/8 GP monster!
