Left- or right-hand traffic
In one country there is left-hand traffic, in another there is right-hand traffic.
Explanation
It is often impossible to explain why right-hand traffic has been introduced in one country and why left-hand traffic has been chosen in another. Whether this will ever be solved in the world I do not know. I am not worried about that either.
HistoryDictators such as Napoleon and Hitler have made right-hand traffic compulsory in many countries. |
