Re: Manual?
About 30 years ago I was off the road for over a year (tried to snowboard aged 42, broke my neck) and when I restarted driving I decided to teach myself to left-foot brake as I felt like I needed a challenge. It was too, left leg is programmed to stamp down hard on the clutch, then release it slowly, so braking wasn't exactly gentle to start with. Took about 18 months for the "intelligence" to move from brain to spinal cord to left leg but after that the reflex was fully programmed in and I'm pretty sure that the half-second gained by not having to come off the accelerator onto the brakes once saved me from a serious coming together with an errant white van man who came straight out of a side turning.
The technique is pretty fail-safe as if I ever get confused I end up with both feet on the brake which is no problem. I still occasionally drive manuals and have no problem adjusting to using a clutch when I do - spent time last week hammering around Brands Hatch circuit in a Dodge Hellcat and a 1966 race-prepped Ford Mustang (bloody great iron V8 up front, race tyres, no power steering, insanely heavy clutch) as a birthday treat. Now that I have to renew my licence every three years it seemed like a good idea to get my driving independently assessed :-)
