CTRA rules 7.2
Mid-Race Joining (Waved Blue): Drivers who have joined the race after the race has begun, or who have rejoined the race after pitting/spectating, are allowed on the track solely by the grace of the race marshals. They must not impact the progress of the current race or its competitors in any way. This includes, but is not limited to:
*Closely following a competitor
*pressuring them or feigning overtaking moves on them;
*Obstructing the track for competitors
*Overtaking competitors
*Voting to restart an ongoing race.
And yet, there are many tracks the majority does not want to drive. I really have the feeling diversity is not something that is welcomed by the crowd. There are too many hotlappers who like to do their routine on the tracks they know best...unfortunately.
It should be as random as it gets without taking recently served tracks into account.
This means it is as likely you will get blackwood GP after South City Classic as getting South City Classic again statistically speaking.
I do like having the occasional rally layout but unfortunately the majority will vote it away.
My experience is that many people do not like to race any track they do not know well, or have a setup for which someone else has proved it's quick there.
Only Beeb 1 and 2 are available in the Netherlands but this coverage sounds like a good alternative for the oversponsored show it has evolved into here.
