The problem isn’t people riding scooters politely on sidewalks along McDowell and Dawson. It’s the ones flying through blind corners without slowing on Fayetteville from, say, Martin or Hargett. Then they sneer at you, the pedestrian, after nearly running right into you at full speed.
I’ve seen plenty riding full speed on the sidewalks on West and Martin around the Dillon when there’s not a single car on the road. Sorry, but that area is not an unsafe place to ride in the street.
That said, I’ve seen more people riding appropriately on the street lately, which is is good. The beauty of the grid structure downtown is that no one is required to ride scooters on Dawson or McDowell because there are much safer alternatives. Even as a pedestrian I often choose routes that keep me off those roads because they are so car centric and dangerous for everyone else.
And as a point of clarification, congestion doesn’t necessarily equate to less safety when it comes to traffic. In my experience cycling, more cars moving slow is much safer than fewer cars moving fast.
