Many years ago, one of the first things I noticed was why are electric scooter rotors on opposite sides?
 if you've come from a mountain bike background as I have that was one of the first things that made me scratch my head I thought it was a technical reason why scooter manufacturers didn't do this,but only a handful have and I'm lucky enough to have bought a scooter which has done this and doesn't it look so much aesthetically better
