...pretty sure I met one last night on the way back home - 3 mopeds & 1 quad, no lights or reg plates. I got suspicious when they seemed to get excited at my presence (initially I thought they were just worried I was police), and very concerned when they sped up and followed me. Now, it could have been teenagers knowing the power of fear having a laugh, but of course I couldn't take the chance and sped off. When I got caught at lights they closed up, and they were definitely trying to position themselves, so I jumped the red and did silly speeds til I got away...
