The Norfolk, VA police department bought four Segways to use in junction with bike patrols, not replace them. The Segway is supposedly more "people friendly" than a bike officer. There was a nice story about it on the news but not so great a story on the
WTKR website.
Don't laugh at the picture of Bob Matthews - he doesn't normally look that goofy. He actually learned how to drive the Segway in about 5 minutes and he was pretty good.
