I don't know how it is where you live but in the San Diego area E-bikes are everywhere and most riders don't obey the traffic laws. Many of them blast through stop signs, don't use hand/turn signals, ride at night without a headlight, etc.. Where I live, many of the kids in middle and high school are riding E-Bikes which cost $1,200 - $2,000 each. They'll ride double or triple on a bike. Many times while taking a walk around town I'll see a kid about 13 or 14 riding an E-Bike one-handed and looking at their phone in their other hand. It's not just the kids that are the problems, it's also the adults over 45 that are the problem too.
I'm not opposed to E-Bikes, I ride a regular 24-speed pedal bicycle, but I seriously think children under 15 shouldn't be allowed to ride them. I also think E-Bikes should be registered, anyone under age18 needs to complete an E-Bike safety course, E-Bike rides must carry some form of government issued ID in case they're stopped by the police for traffic infractions.
Have E-Bikes become a problem where you live?
