Is it any different from the old practice of slowing to the caution to let a teammate back on the the lead lap? How does it differ from a restart where the inside car lets his outside line buddy pull down so they can run together? Hell, Daytona and Talladega are now based entirely on drivers looking for someone to help them.
I don't like this but if it's 'manipulation', it's not the only example. Like the others, it's NASCAR's call and they seem to be okay with it.
As to rules changes, are they going to mandate the pole winner take the first stall? What if the #11 and #18 had been 2nd and 3rd in Q? If Denny had left stall 4 open for Kyle, would we even be having this conversation?
