I’ve managed 13 wing mirrors in 1 street in Bury St.Edmunds.
Trashed a full 500ltr fuel tank on a kerb at Batleys C&C in Hull.
My “piece de résistance” was probably an SLK merc that tried to undertake me while I was swinging it around the old Black Cat roundabout straddling both lanes, and the trailer wheels ended up and over the O/S/F corner of the SLK bonnet
