First off, this is exactly why tracks should just mandate the Novak motor. These headaches tend to go away when we are all on the same page. No worries about this motor or that motor.
I'm not sure about what the NEGS will do for the big races, but last year I was at the Gate's race, and it was Novak only.
As far as lap traffic, yes you should let them by. There is an old rule, called the 3 corner rule. 3 corners and you will be punted
That is not what TA racing is about, however, holding faster guys up is not what it is about either. We all need to work together on the track. That is what makes great racing
