Almost everyone has a cell phone now and many have built in GPS capability. Most cell phone networks are offering location-based service (LBS) to easily identify the whereabouts of an individual.
Some of these are combined with a web based service like Loopt to identify a precise location of a friend or family member. Wherify and Sprint Family Locator are two other examples of this technology already being implemented around the country.
This type of technology could help ease concerns when accepting rides. Now you can easily find the location of your family and friends through their cell phones.
