Google 'Fix My Street' - I've used this twice to report 'abandoned' cars outside my house. I have a very awkward entrance to my drive, sometimes people park vehicles larger than an average car very close to my drive and block my view of oncoming traffic (I have to reverse out on to my street), making it a game of Russian roulette getting out without someone driving into me.
The last time it happened, someone parked a VW Transporter about 6 inches from my drop kerb, for more than 2 weeks - clearly not abandoned, the owner lived on another street. I reported it via that website and 2 days later, it vanished. I've done the same before with some clown in a Qashqai - left parked for a week and a half.
Reports go straight to your council so they can't ignore them.
