Police in CHCH at least really could not give two stuffs about red light runners, tailgaters, slow drivers, those on their phone etc. It's the wild-west out there, especially red light runners 2-3 seconds after the light's red.
Honestly, there's zero fear about being caught, because your chances of doing so are less than 1 in a several thousand trips (for most people).
You can sit at ANY major intersection in CHCH and see at least 1 in 5 on their phone. They don't care.
