One market is for employees of companies that monitor their employee's 
position vs time using GPS.  Truckers, security guards, etc.

"Gosh boss, the traffic was terrible, no I wasn't taking a nap"

ANother market is paranoid (not in a clinical sense) people who are 
worried about being tracked by a hidden GPS tracker on their car (e.g. 
your spouse has hired a PI to follow you around)
