IME in NYC the R7s red light/speed cameras detection leaves a lot to be desired. Waze is a lot better.
The problem with Waze is that it doesn't announce an upcoming speeding camera unless you are driving at a speed above their threshold. If you start driving too quickly after where the announcement would have occurred, but before and through the camera zone, you'll never get a verbal warning.
What exactly about the R7, in this regard, leaves a lot to be desired? Are any other detector models better in regards to cameras?
