I personally couldn’t care less, as long as everyone follows a sensible pattern of being courteous and thoughtful to each other. Forcing others to get out of their way is not a sign of good behavior, whether expected by a battery operated bicyclist or by two skinny bicyclists pedaling furiously side by side - they should go in a single file, especially when there are others on the path with whom they must share this public facility.
The only thing I would find disturbing is when someone incorporates a single stroke lawnmower engine (or it’s equivalent) in their bicycle and uses the bike path… even if he or she is only going 14MPH. Too noisy, too smelly and others aren’t on the path to inhale partially burned gas and oil. Fortunately, I have witnessed that only once in decades.
