I have never seen anyone ride sidesaddle on a scooter or motorcycle before, holy wow! That blows my mind.
Years ago I had an electric scooter (it wasn't a street legal scooter, it topped out at 11 mph) as my transportation and I loved it. One time I did a bunch of shopping with it and had what would fit in the tiny trunk, but otherwise my cloth bags were strung from the handles and held in between my feet on the platform. The lady at the bookstore (which was my last stop) saw me carrying all my bags and asked why I didn't leave them in my car - I explained that I had no car, I was on a scooter. Her face when she was exclaiming aloud wondering how I could balance all that on a scooter was pretty priceless. XD You do what you gotta do when you are not a car driver. I imagine in China it's probably much safer to be a scooter and motorcycle driver as so many people do it, whereas here cars will plow you over like you don't exist.
