I've never had it done to me on a commute. Of course my commute is mainly downhill on the way in, and uphill on the way home. There is no reason to draft on a downhill... not much pedaling required. Uphill, well at a peak of 13mph on the climb, I'm not sure anyone is benefitting by staying on the back wheel. When I commute with my e-bike, I maintain 20mph on the uphill. You're welcome to stay on my back wheel if you would like as we zip past the roadies. (However, I don't think you can keep up)
