Is this why Police often ignore mobile phone use?

osark:
From what I understand if the vehicle is stationary in traffic or not is not relevant, even on a red traffic light. The use of a mobile at the wheel would still be illegal. Unless you are parked in a safe place with your engine off.

This was my understanding, i never answer my phone unless the engine is off, a bit scary when you are going downhill :wink:
