Can't see that it's quicker, essential for old cars with 'crash box' (no syncromesh)
Also on a proper flat-shift set up there will be an ignition cut so you get a back fire BANG!! during gear changes. Can be actuated by clutch switch or load cell/micro switch gubbins on gear lever.
In the video above, the driver is double de-clutching when he's down shifting? In a box with no syncro, I always thought that you need to use double de-clutching on up shifts too?
