Can't or are not allowed to? Because Segway sightseeing trips are quite popular in big european cities, and from what I can tell, the devices works very well on both roads and pavements.
Only american tourists do that.
They are courteous and the Segways are silent, but something still irks me about them.
The tourers mostly look quite fit so probably they could just walk instead. Why bring your whole Segway caravan into walking areas of old towns?
Not allowed to, in many US localities. Segways are too fast for sidewalks, posing danger to pedestrians. But they're not fast enough to merge with car traffic on a road.
Where do they travel in European cities? Bicycle paths?
Chicago does Segway tours through the city.
DC does too.
And they are an unbearable menace. Something about being on a segway makes people think that it is okay to run over others.
