Segway recalls 23,000 Personal Transporters:
Hazard: The personal transporter 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.
My favorite part of the hazard statement "the rider comess off and then back onto the device within a short period of time.". Translation: Fall off, jump up and declare that "I meant to do that!".
Yes, I'm obsessed. Because I can't afford one!
