In London, England, where the roads are narrow, the parking spaces are limited and we have plenty of availability of vans that can actually fit things in, we still get these a*holes with their unnecessary large pick up trucks made for a road system completely different to ours…
These spaces are wider than usual and long enough to fit them but they still have to park like w*nkers blocking the only footpath around!
I mean, I have a 5 door hatchback and know that my car overhangs the back wheels, as does any primary school kid drawing a car…
Check local laws about blocking sidewalks. You may be able to report them to a parking authority. Also, it may be illegal to have a hitch like that on the back while not actively towing (in some states in the USA it is).
This is the UK, there are no regulations regarding parking on or blocking the pavement except in areas where it is specifically posted on signs (which are not super common). You could possibly use a different infraction if they were over the path and parkeds on zig zags for example but they’d be issuing for the zig zags and not the pavement.
It also looks like a supermarket car park which is private property therefore any of the rules based around parking dont really apply, only what they deem necessary to display and enforce. They only usually make any money from camera controlled entrance and exits enforcing maximum stays so that is all they’d ever enforce.
There is also no law regarding keeping the toe hitch attached to your car regardless of use or intent to use.
