Reverse and hit the bollard, bending it, the bollard goes under the car and the owner realise the fuckup and try to go forward, the bollard that stuck under the car is now hooked and then bend upward, piercing the car.
Looking at the second picture, the base of the bollard is rusted and bended and seems hollow, and the plastic part of the car is warped. There's a bend mark on the bumper, she must've force it through even though the car doesn't seems to move. Average SUV driver if you ask me.
there's yellow paint and an indent on the back of the car, in the path of the bollard, which looks quite real to me and feels like a lot of effort to go into for an internet post
edit: now that i think about it some more, and look closer, i'm gonna wager that they did really hit the bollard and maybe fucked up the car, but they then posed things to fake the bollard going through the car. It's convenient how the first photo hides the base of the bollard and the area where it would pierce the car, and the second one could quite easily be two separate photos with the middle of the bollard erased to match the outline of the car's rear.
That would be a lot of effort for a very high quality fake. In both pictures you can see the whole bottom of the trunk was raised up by the bollard poking through.
My bet is (if real) they backed over it so it was at like a 45° angle or something, then drove forward, but the top of the pole caught the car, straightened out, and went through the trunk.
