Doohan was onr of the best at going sideways. He used to do it all the time 'till he belted a haybale one day and came down... he spent less time stuffing about after that... and more time winning.
The photographers used to wait at particular corners where they knew he liked going sideways... I remember reading that the pro-photographers called him "The King of Slide".

Gary McCoy's not too shabby at it either. Rossi used to like following McCoy cos he loved how sideways he got it.
