No, actually in my area they decreased. The bicycle shop we had for twenty years closed, probably because the price of enthusiast bicycles were getting too high. We had a phase with razor gas and electric scooters and hoverboards, but they died too.

The scooter thing really only targets the college student, and the adult who lives like a college student. Single, spends most of their time on or near a campus be it school or work, etc. It can't really scale past them, because that form of life is extremely limited compared to others and congenial to it.
