Calgary has the same setup, I'm sure it's a form letter and mostly automated. Or at least I remember hearing about Calgary having that on the radio.
I agree that it doesn't actually do much, though maybe they track the # of times a person gets reported? We should get 4X4's plate # and everyone can call in all day
Yeah I wish you could actually call and get a cop to check something out when you see a real drunk driver, but unless you follow the guy it'd be kinda hard to find them even a few minutes later.
