The lead car sets the flow. If you're doing 35 in a 35 and someone comes up behind you going 50, they can either accept that the flow is 35 or they can be an aggressive asshole.

And for the record, if a cop really wants to, they can absolutely pull you over for going 80 in a 65. It doesn't matter if that's the flow of traffic, speeding is still speeding. It's just a toss up if you pass a cop that doesn't care or not.
