Where I live they fall in two camps. Legitimate commuter use by commuter veterans with all the necessary kit, skills, and route knowledge from their years of doing it. And they usually own a commuter specific model optimized for that use. Often university professors to and from the local place.

The other group are the idiots who are trying to end-around the local laws forbidding gas motor dirt bikes on streets and greenways by buying these 1000w+ e-bikes with motor bike tires and throttles that bash around as if it is a motocross race.

The commuters, probably could draft fine, but legit commuters usually don't own "modded" throttled e-bike dirt bike style bikes. So theirs has the factory speed limiter. Meaning you would be faster down a hill past them, then slower up the hill. So wouldn't work really to draft unless it was really flattish.
