Not sure what cruise control has to do with this. Different cars have different acceleration speeds and there are conditions that rebalance traffic based on acceleration like traffic light or a slow moving obstacle. Also if you live in high speed highways there’s always more space for variability as not everyone is always comfortable pushing the limit.
there are people who can’t keep a constant speed on a flat road. it’s annoying to have them pass you only to have to pass them again thirty seconds later. repeat a few times for annoyance.
