The police officer didn't think it was funny.
Edit: Just noticed the pounds sterling. I'm in the USA for reference.
The police officer rang my doorbell and ordered me to move my car, as blocking someones car would be an offence (disabling personal property).
I asked the officer to give the offending car a ticket but he couldn't do that as it was on private property and thus a civil matter. It was also not illegal for the car to park on my private spot as I don't have a gate which makes the apartment driveway an extension of the public road, and thus usable by everyone. Dutch law is complex.
He was probably confused by the rule that you are not allowed to block an exit ("uitrit") of someones driveway of proprety by parking in their way. But that rule does not apply if you're parking on your own private property.
