I am a disabled driver and live in a very narrow close. I am frequently bocked in by visitors to other houses parking opposite my drive way . I have had abusive language and threats when asking people to move and have reported them to the police - no action taken. I believe that the pavement is in law part of the highway and that it is an offence to obstruct the highway.
I cured one of the perpertrators when I "accidentally" put a large dent in the side of his almost new honda civic with my then old banger. I refused to accept liability and counter claimed for damage to my vehicle. All action was then dropped and He has never parked in the street again
