I have a Segway.

I always stop when other people are walking toward me on the sidewalk; it makes them more comfortable.

The other important thing to watch out for are blind corners - where obstacles prevent others from seeing you. I do my very best to stop so that I don't surprise anyone.

Why doesn't this guy just push for the ability to issue tickets to impolite Segway users instead?

Banning Segways has repercussions that this guy probably hasn't considered. Remember that nationwide, well over a third of all Segway users are physically disabled in some way, and around here, at least two of the three owners that I know are.
