It also seems rather short, and leaves the reader wondering if the researchers could have done more to create a more vital and important document. They did not find the Segway was unsafe, however, and many of the comments of the postal employees who used it were very positive. Other studies go father than many of the findings in this report, including the safety of the transport itself. Another study notes, "The Segway PT and its rider were found to have the second shortest braking distance, highest sight lines, one of the smallest footprints, and quickest perception-reaction time" (Landis, Petritsch, and Huang, 2004, p. 97-98). These are concrete safety details that seem lacking in the other report, and it seems as if the report could be much more useful if they had included data such as this in the report. In addition, Segways have been recalled due to accidents while riding, which was not included in this report, and should have been. Another report shows that the Segway can shut off at once if the pitch of the road becomes too great, or the batteries go dead. Several people have been injured as a result of this rapid...

Segway recalled the units in 2003 to add a software upgrade to stop them from stopping abruptly when the batteries die, but other problems with pitch and with the body movement of the rider continue (Arnold, 2003). Thus, all the safety concerns of the Segway are not addressed in this report, and so, it is flawed in many areas.
