If you have a witness, press for charges/follow up. Plus this lads possibly driving whilst SORN/Uninsured etc hence the 'interest'?
The deliberate action- If that was car v car or pedestrian the driver could be issued with a section 59?
Glad you are ok Hadge. I had an idiot move and I caught up/followed the fella to his Police station swipe/carpark- then proceeded to ask him if he was proud of himself as his (assume) colleagues went past him into work.
If you genuinely feel it was a drive at you and you were lucky- speak to the duty Inspector. Ask why this isn't in the public interest.
No idea about the technical terminology the Police use but if you make enough noise/complaint even they can't tell you to go away.
