Do you have any of those funny PCSO’s around? I know they do bugger all in real life but if you approach your council they should be able to point you in the right direction. I would always keep reporting this kind of driving to the Police in the first instance then insist they do something about it. If they say “we can’t, we’ve no evidence” then ask them What evidence they need apart from a body.
About 8 years ago my next-door neighbour had mate who used to drive like a looney in our cut-de-sac, positively come to a screeching halt outside his door. We have a very quiet cut-de-sac with some great neighbours, so one afternoon during a summers day we kinda waited outside with all the kids kicking balls, riding bikes etc. and almost bang on time (about 5pm, after the football finished) he came screeching around the corner only to find us lot outside. I have never seen the whites of someones eyes through a car windscreen before, but we did that day. Then our resident Paramedic walked over to the car, opened the door and promptly punched the bloke on the face.
He never came round again. Next door neighbour came round to each house individually and apologised to us all.
Whilst creating a situation that could have turned out bad, it turned out good.
I wouldn’t recommend you do this though, you don’t know how stable the personality is do you.
