To be honest, the classic Mini sump is not much higher. It would be interesting to get a measurement but I would be surprised if it was over 4 inches clearance. The Mog is three and a quarter on the low edge. I believe that speed bumps are restricted now to three inches, although some higher ones are around. Hopefully after one or two accidents involving snowploughs, they might see sense and lift them all. Speed bumps are as cerebral as a bloke with a red flag IMO.
