Is this to stop theft?
I’d imagine that’s a benefit, but the design was probably for structural integrity. Last thing you want is for someone to lean on it, tipping over, and then rolling down a hill or something.
Or a bomb
Now I’m left wondering who filmed that video, they clearly knew the bomb was about to go off
Generally, someone involved in planting it would have phoned in to a newspaper and been like “I just planted a bomb at this place lol”
Theft and the fact they tend to be in locations (like street corners) where cars may crash into them.
There’s a really OG mailbox in my town, it’s bent a full 10° towards the house it stands in front of, has classification as a historical relic and all, that has been run into by cars at least 3 times per year since cars were around.
It is still standing.
At one point (around when it got its classification), they put safety poles around it.
Until they got removed, they ended up getting replaced every year because they were all bent to hell from new accidents.
Perhaps they need more speed control in that area?
