I had a simillar experience a few months ago with with a couple of twist and tw*ts tail gating me but unfortunately for them i was in my crappy old escort van so i braked a bit late one hit the back of the van and the other missed it but fell off trying to avoid me. i was only doing 30 so no damage to me but nearly pissed myself laughing, the other thing that made me laugh is several people stopped and they got such a bollocking hope you and the car are ok they just really hack me off.
