The City of Barcelona is banning Segways from the central portions of the city. They are considered part of the class of transportation that could be called "novelty urban transit". Like duck rides in Boston or beerbikes in Amsterdam, they ensure that tourists have a visible impact on the city they visit. In a cultural setting they are the equivalent of poor ecotourism.
Writing on The Atlantic CityLab Feargus O'Sullivan says, " It would surely be going too far to damn Segways as Satan’s chariots,
but they still need to go. Barcelona’s waterfront should be an open-air
living room for the city, not a place where the experience of the city
is simulated for motorized, walkway-clogging tourist groups."
