I have been on Stromers for 6 years in the DC area. used to live in Chevy Chase and now Falls Church. the worst I have had are some serious Lycras crying cuz i passed them a couple times, not in groups but when they were solo. I live on the W&OD frequently going to Purceville or back through Montgomery county out the C&O or up to Lake Frank and back down Ga Ave or trails into DC to MGM or MT Vernon. Not one legal hassle just a few individuals. I am not perfect on the trails going a little fast but always polite, apologize when needed , try to not make anyone have to move or brake due to my riding.
I also always have my panniers on. try to hide the motor, dont speak to anyone unless stopped and even then act my headset is loud even though it isnt, no hassles. If I see a smiling or non threatening person speak i will answer questions, I tell them it feels like being in Disneyland every day except minus the crowd when ever I ride...
