The problem I see with the e-bikers is that they just can't ride even at 20 mph. They don't fall off the bike because it moves fast enough but otherwise they are completely inept: break with the rear wheel only, can't stay in the lane, can't corner, don't signal turns, don't warn when passing etc.
20 mph is a moderate speed for a road bike, however, you need to ride a lot to comfortably get to this speed and as a result, when you get there, your skills are adequate. A roadie riding 20+ mph is not going to enter a blind corner in a left lane or skid out trying to maneuver around some trash on the path. Why should we punish people who bike for exercise? It's not like e-bikers are going to wipe much less at 20 mph, your 100 lbs "sauron" without front brakes is going to skid even at 10 mph.
