How can there be traffic if there are two empty lanes? We’ve already added more lanes, the traffic has been solved. If the ambulance needs to get through, they should add a fifth lane. (/s)

As an Austrian, this works good but not always so good as it should

In Paris, government people and/or VIP use fake ambulances to take advantage of this and avoid being stuck with us peons.

Yep, we do not have the wide ass shoulders on our Autobahn network. We also know how to merge using the entire merging lane and the zipper effect. In the USA, it's cross the white line at lower speeds to create an accordion effect.

Lucifer! We can't even keep cars from blasting down the shoulder.
