I’ve just stepped onto the factory floor at Segway world headquarters in Bedford, New Hampshire, when two engineers sporting matching jeans (tapered), shirts (plaid) and hairlines (receding) glide by and shoot me matching expressions (grins). “Doesn’t anyone walk around here?” I ask, as the distinctive, almost melodic hum of the Human Transporter (HT) trails off. Segway development engineer David Robinson responds with a different expression, this one more quizzical than the one on his colleagues’ faces. “Would you?” he asks.
