after seeing my grandads old velocette motorbike 50 + years old and that had sequential box it hit me that why don't more cars have sequential boxes in it's not like it's a new technology you would hae thought that would be easier for any one to use push forward to go down pull back to go up you would think that any common road users would find that easier than going in and out of gears plus whilest your in motion you dont need the clutch easier so you can left foot break! can anyone tell me why no one has done this on a commercial scale apart from the super car companys
