I don't care about any of that. I'm fat and old now. I care about the danger of very high speed users who don't have the skill to handle their machines in close quarters with me, my wife, my kid on the bike paths.
Realistically e-bikes as they're being sold - limited to 20 - don't present any more danger of that than conventional bikes. Of course it's possible for an unskilled user to go faster than they can handle, but that's always been possible on a conventional bike too.
