"The Historical Reasons Behind Driving on the Right in America and on the Left in the UK"

The difference in driving sides between the US and the UK dates back to historical and cultural factors, with the Conestoga wagon playing a key role in the US. While the US and most of Europe drive on the right, the UK and a few others drive on the left. The French revolutionary government and Napoleon influenced the switch to right-side driving in Europe, while the UK's preference for left-side driving was influenced by the prevalence of small carriages and individual horse riders. Driving on the opposite side can lead to serious consequences, so extra caution and reminders are recommended for those driving in a country with a different driving side.
