what happened here?

Unless we decide to go for yam char, Paula and I go to Tai Fah Wut (Fairwood) in Queen’s Hill Estate for breakfast. There is only one road leading into the estate, Lung Shan Road, and a few days ago, as we were walking along the path running alongside this road, before reaching the entrance to the estate, Paula spotted this on the other side of the road:

This is an enlarged view of the previous photo:

It’s cleat that whatever vehicle flattened these four hooped railings, which are there to block access to the cycle track, was travelling from left to right; in other words, away from the estate. And ever since we saw the damage, I’ve been trying to figure out how it happened. And why?

You can see that the vehicle must have mounted the kerb only slightly, because the lamp-post, which is much more substantial than the railings, was unscathed. Any further onto the pavement and the lamp-post would have stopped the renegade vehicle in its tracks—and the second, third and fourth hoops would not have been flattened. Did a driver lose control of their vehicle? The road here is a broad curve, not an acute bend, so this hypothesis does seem unlikely:

However, my final photo contains an important clue:

Notice what appears to be some kind of hazard road sign lying on the ground in the foreground. I would conjecture that it was originally located in the hole where the brick paving has been disrupted, and it was subsequently moved to the location shown in the photo so that it didn’t impede access to the quasi-industrial premises that you can see in the first photo above (the entrance is marked by the parked car). So it appears that the culprit driver deliberately mounted the kerb, flattened four hooped railings and drove between a second lamp-post and a plastic bollard on the cycle track, flattening a hazard sign in the process. But why? Access to this site is provided, as it is for several other quasi-industrial premises along this section of the road, direct from the road. Strange!
