In Australia, struggling with the inattention of drivers with the help of water and a projector

A tired trucker who does not notice the signs and signals warning of a low bridge or tunnel can cause a lot of trouble - sometimes the truck literally wedges between the tunnel's overlap and the road, blocking traffic for a long time and causing multimillion-dollar damage. In Sydney, they have come up with a futuristic way to warn truck drivers who are gawking at the entrance to the tunnel. If the driver persistently ignores numerous warnings, the water curtain is turned on, on which a huge two-meter stop sign is projected. Since the sign appears directly on the roadway, directly in front of the car, it is almost impossible to ignore it. The video showing the work of the mark resembles footage from a science fiction film. Although such a sign is much more expensive than the usual, a single tunnel repair costs much more.
