I was a driving instructor for a few years back in the late seventies. Pupils were taught that at a stop sign they needed to stop, apply the handbrake and, if necessary, engage neutral. If it was a give way, then approach slow down and if feasible turn onto the main road. If the main road was busy, then, handbrake and possibly neutral.
Problem was, at my local test centre, there were two examiners. One would criticise a student for unnecessarily stopping at a give way sign. The other, who always looked nervous, expected pupils to stop momentarily, so it was necessary to brief students when the examiner appeared and called the name of the person taking the test to tell them which course of action should be followed.
I also count to three at stop signs especially when in France. It is a practice which also has the potential to avoid an accident with a cyclist or motorcyclist since you have more time to notice movement.
I find the current practice at traffic lights of drivers sitting on their footbrake with the glare of rear lights frustrating.
