But let's not discuss Daylight Saving Time. Let's talk of cars and traffic ...
In some countries, particularly in the remnants of the British Empire, people drive on the left. In others, including most of continental Europe and America, people drive on the right. Which is better?
To answer the question, we need to consider the facts. Most people are right-handed. Old Roman tradition was to carry the shield with the left and the sword with the right. Most vehicles still have manual gear shifts. Most shift levers are towards the centre consoles of the vehicle. So I think the better answer can be determined. But there are many factors to consider, and arguments can be made for either side.
However, let's not have those arguments. Instead, every year, let's drive for six months on the left, then for six months on the right. Once in March and once in October we should swap everything round. That makes perfect sense.
