Segways Exist
I might be one of the few people who has never seen a Segway in person. Just now, I look out my kitchen window and the guy who goes around reading the electric company meters is riding one.
He let me take it for a little spin in the driveway. It is pretty cool and it seems that is job is a perfect one to benefit from the Segway. He can get around to the sides of houses easily and quickly and be on his way.
The Segway still seems a little gimmicky to me, but it is intriguing.
