The Rule of the Road

Here in Britain we drive on the left. That isn't new, it has been the rule of the road for over 100 years. It means that if you drive on the wrong side of the road you are breaking the law.
The law is usually interpreted as allowing overtaking, provided it is done safely.
In the last couple of months my wife and I have both been forced to pull off the road to avoid oncoming traffic. That is not driving safely, it is aggressive, dangerous and illegal.

Similarly driving across a mini roundabout with the circle on your left is also dangerous and illegal. Even driving over the central circle is a crime punishable by points on your licence and a fine of up to £1000.
