Really? I ride a bike and I can't wait for lots of people to use e-bikes to get around. Research shows that "the more people ride bikes, the safer all bike riders are on the streets." [0]. Also... I'd much rather get hit by an ebike than a car.
Based on my experience with dangerous ebike riders in NYC, I do think this is a problem. It's just that it's so much less of a problem than cars that it's hard to care about this "gotcha" when we talk about bike infrastructure.
Assuming any US cities focus on bikeability, by the time we've figured things out enough to actually worry about this problem, hopefully the Dutch will have figured it out. I know ebikes are a very real concern in the Netherlands and there's a lot of active lawmaking on the subject right now.
