If (or when) the roads of Europe and America join which side of the road will cars drive on?

The French go through this everyday on one side of the Chunnel and English on the other. The side used is left side in England and right side in France.

Most places in Europe drive in the right side. I can only think of the UK, Ireland and Malta as exceptions right now. They would just have to learn to drive in the right side (see what I did there).

By the time they make a chunnel to the US we’ll have flying cars.
I won’t hold my breath.

Driving in an underwater tunnel from the US to Europe? Riiiight.

Most of Europe already drives on the same side of the road as the US. It’s only us Brits (and Irish) that drive on the left.

The Channel Tunnel solves the problem by having all cars loaded onto a train to pass throught the tunnel so there isn’t any one point where you have to switch sides.

While in a tunnel it doesn’t matter. You just stick to your lane. Probably if they have to choose it will be right side of the road. Especially if the tunnel goes from the US to country in Europe that drives on the right, which is most of them.

They could even have two separate tunnels, one for each direction, and have them cross over each other in the middle.

@downtide I thought of that, but also thought that might be much more expensive to build. I don’t think it matters. As the cars exit the tunnel there would be warnings what side you are driving on and some sort of lead onto local roads and highways.

We drive on the right side of the road, that is to say the left.

@talljasperman I am curious how you came up with this Q. Why woud anyone want to create a tunnel that long a distance? Maybe US to the Bahamas is more practical.

@JLeslie a tunnel that big would be impossibly expensive anyway. Whilst we’re talking impossible things, why not have two tunnels that cross each other?

Good point.
