The NYPD bought 10 Segways. I'm not sure why, other than being nice for the tourists. I remember a few years ago seeing the five-oh in Chicago rolling about with them, and it makes you want to laugh.
This was the machine that was supposed to revolutionize our cities and society on a whole.
Years have passed and no one has really taken notice, other than a few Police Departments, and many countries have banned them completely pending new legislation or safety studies.
For now, the Segway will be continued to be used by G.O.B. or Bananagrabbers.
