Simon Property Group, a company that provides security solutions to corporations all over the U.S., has announced that it is rolling out Segway i2s to its entire fleet of shopping mall security guards. The latest purchase will make Simon's fleet of 225 Segways the largest in the world. Apparently, the mounted security guards have been a hit with pedestrians, which provides "social interaction" that would otherwise be impossible and allows the security guards to do a better job of keeping the peace. Say what you want about the Segway, but you must admit that they are noticeable, which is definitely a good thing when it comes to security. If you frequent malls in major cities like San Diego, Las Vegas, Houston, Miami or Boston, expect to become even more familiar with security guards mounted atop their trusty steeds. There's just one more question to ask: just how green will they really be?
