"Is dangerous cycling a problem" BBC

This is true if you rely on the syncromesh to do it, not so if you use the throttle to match the speeds in the gear train as you go down.

If you get it right you don't need to use the clutch at all- into neutral, blip the throttle, into gear.

I don't do this with my car, but hire cars are fair game.

I went Clutchless before anyone else did it. It's so much more 'zen' like and encourages you to look further ahead and 'read' the road, it's better in heavy traffic allowing you to 'flow', it's cheaper, has less parts to wear out and it makes you look cool.
