Blocking public pathway

For the past two years, I have been unable to utilise our public pathway due to my neighbor's son-in-law consistently parking his car in a manner that obstructs the pathway and violates social norms and acceptable behavior. I have engaged in a conversation with my neighbor, expressing my concern that the way they park their vehicles is obstructive and impedes the free movement of able-bodied individuals on the public pathway. It is crucial to recognise that the public pathway is a shared space intended for the use of all residents across the street, and any blockage or impediment that restricts its usage is unacceptable. I have attached picture that speak for themselves and to support my claim.
