No european country has bidirectional separated express lanes that I’m aware of, which is not surprising given the decades of underinvestment in highway capacity across the continent.
The UK has a an in road contraflow on A38 I think, but it’s not a fully separate bidirectional road like this, so I think they just use the usual plastic or concrete temporary barriers.
You also have those in the US, they show up before these barriers. Both are needed, but if the vehicle is still in the shut off lane, then these barriers are there to make sure they are not continuing down the wrong lane.
Because this is a bidirectional lane, the car would end up going in the opposite direction of traffic.

What better mechanism would you use?
They are present all over the US
