From a visitors perspective, I flew down for two days at the state capital, and used a scooter liberally riding around downtown, and the campus of Georgia state university. I did not see the littering of sidewalks at all. I saw people riding scooters in the street, and on the sidewalks, but even with a lot of people I didn’t see anything of what you’re speaking of.
Scooters are great, they are low-cost easy way to get around. I think anger in Atlanta towards the scooters, is similar to why Marta will never go up 75.
