Maryland ranks No. 1 among the states in frequency of global positioning satellite use, the GPS information firm TeleNav reports.
The company ranked cities in states in several categories, from the serious to the frivolous, and found Maryland atop the heap in putting the navigational technology to work. TeleNav said Maryland drivers used GPS at twice the national rate. The company did not venture answers on why Maryland would top the list, but the state's relative affluence and robust high-tech and defense industries could be factors.
No. 2 on the list is the District of Columbia, followed by Massachusetts, North Carolina and California. Rhode Island, Virginia, Georgia, New Jersey and Tennessee round out the top 10.
Maryland ranked ninth in terms of the likelihood of drivers to use GPS to get around a backup. The leader in that category was -- no surprise -- Los Angeles, where there are so many backups to get around. Los Angeles also led in total GPS-guided trips, a category in which Baltimore ranked 15th.
Other findings included the nuggets that Wal-Mart is the No. 1 business sought in GPS searches and pizza the most likely food to be sought by satellite.
