Tbh bud it looks like that was a particularly badly run day with all that aggressive diving up the inside at corners, and every TDO I've been with would've cracked down on that straight away. I forgot that CC is an overtake on the RHS circuit though, haven't been there for ages.
Overtaking should really be by consent only, especially when you have mixed abilities and car speeds like that. Come and do a normal day with the rest of us, you'll love it
