While overtaking a lorry on A4232 at normal speed, this idiot flew up behind me and started gesturing and flashing his lights. Shook my head as he sped past, he cuts in front and slams on the brakes. I overtake as I don't want to stop with a lorry doing 60mph behind me and he stays alongside, hanging out of his window telling me to "pull over, let's have it then" as well as some other ramblings. Basically did this for about 8 miles, absolutely nuts, think he was on something. Only got him to drop behind when I held my phone in the air and he thought I was filming. But even then he was right behind me, weaving back and forth like an absolute lunatic.
