We need some kind of rule of thumb when driving, similar to aviation’s “aviate, navigate communicate”, but for driving.

“Operate, Communicate, Navigate” perhaps?

*Operate the vehicle *Communicate with other drivers, use your indicators, drive predictably *Navigate to your desitnation

Or in a single paragraph:

Operate the vehicle, make sure you are operating the vehicle with reason and are following the rules. Once you are doing this you communicate withe the other drivers, indicate and drive predictably, Once you are doing this, you can start navigating.
