Are you even allowed to bring a 125 cc onto the highway? in Florida i think 250 is the minimum CC you have to have to get on the interstates. That's for a good reason too, the speed limits are 70 mph, often times the cops are not even going to start waking up until you are doing 85 plus.
I was talking about city streets once you get past the freeway underpasses, where the lanes are wider and people go a lot faster. The 125+ cc is the only one that can still keep up. I have done some dumb things in my life, but I wouldn’t ride a 125 on the freeway

.
scooters do serve a purpose, but people on both sides of the 'obstacle' need to mind their ego's.
The scooter trash who won't move over to let the cars go by is a big problem, pissing people off is not how to stay alive.
The jackass in his cadillac, who can't wait 30 seconds to get in a safe area to pass the guy on the scooter, jesus asshole, you can't wait until the road opens up in a block to go flying by at 70 mph without running the scooter off the road, WHO by the way has just as much right to be on the road as you do?
Then you got both sides who are too busy looking at their phones, and running into each other that way. 
In this case, I was actually on a pedal bike where there’s a big downhill section. It’s one of those funny, narrow and low-visibility 2-way roads through Golden Gate Park in San Francisco. The speed limit is 25 MPH, but anything faster than 15-20 MPH isn’t really safe in a car because someone can come around the corner pointed right at you with no warning. On a bicycle, though, the slope means you can come down at 30 MPH, and it’s very safe because you can ride all the way on the right side of the road so there’s no oncoming vehicle risk, no intersections, or any other risk factors. This joker decided he wasn’t going to get left behind by a guy on a bike, so he took the blind 20 MPH turn at 50+ fully in the oncoming traffic lane. It’s not a busy road, but it’s not lonely, either, and cars come through all the time. I’d say he had about a 1 in 5 chance of a head-on collision that he wouldn’t have been able to avoid or survive.
ahh, but, you can't take a scooter on a bike trail, you'll get ticketed in a heartbeat... and that bike trail, lets you beat that 35 minutes of morning bullshit traffic jam, and 45 minute bs jam coming back home. your e bike with it's pedals, you get on the bike trail and 5 minutes later are on the other side of the mess.
no neither the bike or scooter is really built to handle potholes. At least on a bike you can go flying off and hopefully find a patch of grass to go rolling to a stop in. in a golf cart or other enclosed 'vehicle' you are kind of trapped and smashing that windshield at 20 mph is going to be absolutely devastating. THAT is why the speeds are limited on those things, because past that speed you now need seat belts, and all the signaling and stuff a real vehicle needs.
now lets take a 15 yo, put them on a 'bicycle' that can do 30 plus mph and let him go flying around on the sidewalks around the shopping mall, scaring the little old ladies with his acrobatics. but is he really any worse than the gixxer tard doing his wheelies and burnouts in the middle of the intersection waiting for the light to change?
As an interesting twist. your little bike runs of gas. i am surprised nobody has made a propane one yet. it runs off those little blue or green bottles you can buy at the hardware store. those are also very easily refillable from the bigger 15 lb bbq tanks too. it might be arguably safer than gasoline engines, and might be easier to thwart certain regs too as it's not a 'gasoline' engine.

I don’t have occasion to use the separated bike trails on the levy very often, but I would definitely go e-bike over moped if I used them regularly. I wouldn’t ride a moped on those trails, that would just be a dick move. As far as regular painted bike lanes, it’s not really clear here in Sac whether you’re allowed to use them on an M2 moped, but everyone does so I wouldn’t hesitate. I wouldn’t need to use the bike lane on the slow neighborhood roads, and the bike lanes on the fast roads are empty anyway, so no one is going to care. I would definitely try a propane one if such a thing existed. I have to get the 50:1 2-stroke fuel at the hardware store, anyway.
The “sidewalk menace” debate is complicated. I have definitely seen people buzzing past pedestrians and around corners on e-bikes and e-scooters, so I get why people are upset. However, how many people are actually seriously injured or killed every year vs run over by cars or trucks? So we’re having a lot of debate about the safety of vehicles that don’t kill people and no debate whatsoever about the vehicles that do.
