Sorry folks! IMHO the only way to protect the majority of cyclists, electric or otherwise, is to physically separate them from cars. A few methods have been shown, but due to the cost of bikeways this won't happen, at least not in this country.
Unfortunately this is impossible in most cities. To have totally separated roadways would also mean totally separated destinations...and that's not how it works, if you're using the bike for your main or only transportation, and not primarily for exercise or entertainment.
There's no way to make a completely independent non-car-road-crossing bike roadway in a city like Phoenix, for instance (probably not in any city). Even if it were elevated directly over the regular roadway, it would not be possible to have a rampway down from it to every place a regular roadway has a driveway or other access point to the rest of the city. It would have to be an "expressway" kind of thing that only has on/off ramps at intervals, and that would be too restrictive.
For example--we have a canal system that includes some good bike paths, and you can only get on and off of it every mile or more.
So at best you must go half a mile out of your way if your destination happens to be halfway between exits---and those exits are, naturally, wherever the *major* fast-speed (40-45mph+) car roads cross the canal.
Other separated bike trails are similar.
The other issue is if there were a separate bike roadway, it wouldnt' be just that. It'd be too expensive to use for just that. So they'd make it an MUT, and be useless for quick travel anywhere, or with wide vehicles like cargo bikes ro bikes with trailers or trikes, because it'd be used by pedestrians, large groups of mothers with strollers all walking side-by-side blocking the entire passage, dog-walkers, etc. After dark, perhaps as late as 10pm, it'd either be closed (like many of the off-road bike trails already are), and inhabited by the homeless (some of whom would never leave), blockign the path. Again, it'd be useless for quick travel. No one but those using it would ever police it.
Also, because it'd be an MUT, it wouldnt' be usable at anything mroe than maybe 10-15MPH, so even though technically I could go 20 on an ebike, I would never be able to actually ride it that fast because of the other people on it.
Almost certainly, regardless of any other considerations, it would be built only wide enough for two regular bicycles to pass side by side, and not wide enough to do safely, either--becuase it'd be too expensive to do any other way.
What really needs to happen is co-education of drivers and cyclists, from a young age, to teach them how to share the road with *all* traffic that is on it.
