Idiot trying to “drift” on a roundabout

Late on a Saturday night a young guy came flying into the roundabout we were about to enter and spun his car out doing a 180. You could see at the time the back wheels were locked up so he was trying to drift/slide around the roundabout.
What makes it worse is that after this he went the wrong way around the roundabout and then down the dual carriageway the wrong way so he could get away faster.
