So, I think it's safe to say people saw this coming:
GLENDALE, Calif. (AP) - A 32-year-old man has been charged with stalking for allegedly attaching a cell phone and global positioning system to his ex-girlfriend's car to track her whereabouts, authorities said...
...Police said Gabrielyan, who ran a music and video shop, used the satellite tracking system to follow the unidentified 35-year-old woman and meet her unexpectedly at a book store, an airport, a cemetery and dozens of other places after she ended their relationship.
"This is what I would consider stalking of the 21st century," said Lt. Jon Perkins of the Glendale Police Department.
At least it's some comfort that this 21st-century technology dilemma was undone by a common 20th century one: the woman discovered how Gabrielyan was tracking her when she found him crawling under her car, trying to replace the cell phone's battery.
