also its on my list to do , i removed the stickers someone had placed on the dials whilst sat in a trafffic jam one day , they were in the wrong place anyway
to work it out its the 6 times table
so your doing say 40kph , ignore the 0 and think 4 ,,, now times it by 6 so your looking at 24 , thats how quick your going
so 70 kph becomes 7x6 = 42 , 100kph is 60 etc etc etc , easy peasy
