In a full on rage about the speedocable coming loose for the 4th time on a old Mini Cooper I oned a few years ago , I speeded over 5 speedbumps with the revcounter showing 5000rpm in 3th gear equaling about 55 mph.
It must have been 2.5 feet in the air every bump I hit , boy what a rush
I scared the bejesus out of guy walking his dog in the same street.
The Mini was toast after that so I scrapped it.
