There are cameras in the tunnel, but officaldum will probably state that the reason they are there is for safety.There should be cameras in the tunnel and any gimp that crosses the white line should be hit with a €250 fine. That would probably fix one thing. For context I saw a guy do it not once but twice today.
Now to me, someone crossing a solid white line, would fall into that criteria so I imagine the next bull shit line they would probably use is GDPR.
