If I bike past 3 miles I'm gonna start sweating, and pushing 5 miles I start feeling it on bad air days. With the scooter you just stand still and don't have to do any special layering. People ride them in suits.
ebikes for sure. Bigger wheels go over potholes better, and only the original bird scooters actually had air in their tires, the rest are just hard rubber that feels pretty rough/bone-rattly on bad roads.
Safety wise, I'd say they are about even. Cars aren't going to value your life either way.
