This is the action of someone who's wholly, truly, and absolutely had enough. We don't know how long this parking dispute had been going on for, but we're guessing it was a long time. There's no way that a one-off incident would prompt someone to hire a steel cage, and then a crane so they could lift the car onto the top of the steel cage. There's no way for the driver to get away from this situation without getting a crane themselves. As parking revenge goes, this is extreme.
It gets worse for the driver, too. Although you can't make out the content of the note on this picture, it contains the contact details of the crane rental company, for the attention of the driver. Apparently, if they want to get their car back, the standard rate for rental is $100. They should have just found somewhere less contentious to park.
