Fortunatly only doing 10mph, just as I draw level the passenger door opens and I perform my first stoppie, landed with a crash but still upright

The passenger is laughing and giving me the fiddler*r sign, door still open

Now I got the numberplate, but if I report him to the police, will they be "interested" in my filtering or just have a go at him?
What do you think?? I'm seriously pissed off as this was done just to knock me off! Oh and never seen him before so it's not someone I've peed off, cos I could understand that!
