My mate hit an a*hole last year when he decided to just run cross in front of us despite there being a crossing about 20 feet away.
My mates bike was pretty battered (needed new front wheel,fork,handle bar and has now bought a new frame as he doesn’t trust the crashed one) as was he, police were not interested at all unless there was a motor vehicle involved or ambulance was required.
Had witnesses, but that didn’t help as the guy just walked off.
My advice, if you’re going to hit someone, make sure to them hard enough to get an ambulance out as that seems to be the only way the police “might” turn up, sadly!
