Visiting the Teotihuacan pyramids, transportation options are needed. Segways can deal with tourism in this area and similar sites.
Provide convenient and inexpensive mode of travel in and around pyramid site(s). I envision with so many people visiting this area and similar sites on a daily basis, using Segways and tour guides can offer a better option of moving the thousands of visitors, tourists and workers/researchers. Further, by employing the local people, you are creating employment opportunities and continued growth in this region and similar sites.
