DocJohn writes, "For the second time in 3 years, Segway has announced a recall of all Segway Personal Transporters. The problem described is that the Segway 'can unexpectedly apply reverse torque to the wheels, which can cause a rider to fall. This can occur when the device is tilted back by the Speed Limiter and the rider comes off and then back onto the device within a short period of time.' A software update is needed to fix the problem." This AP story mentions President Bush's 2003 stumble on a Segway without speculating on whether the cause was the software glitch behind the current recall.
