Segway obstacle course

It was supposed to revolutionize urban transport. But five years after its public debut, the two-wheeled transporter from Segway is still finding its way through an obstacle course of slow sales and technological hangups. The latest bump in the road: On Thursday, the company announced a safety recall of all transporters sold to date because of a software glitch that could cause the wheels to suddenly change direction. This marks the second recall for Segway in just a few years; the first was in 2003.
