I was taught to leave in D with foot on brake for short stop, select neutral for red lights and similar. But that was on an Austin A60 with BorgWarner three speed and steering column selector.
I still think its worth learning to drive a manual, if only just in case. If nothing else it forces a much better understanding of whats actually going on dynamically when driving.
Folk I've ridden with who have only driven automatics often lack feel for the natural flow of traffic.
Then there is herladyship, the girl who re-defined the concept of MadameLeadfoot.
Allegedly passed her test on a manual but recent experience riding with her in a Mini Cooper showed serious clutch pedal operation problems coupled to a near total inability to judge and anticipate traffic movements. Thirty miles on quiet roads and my nerves were shattered. Back in an auto JCW Mini now thank god. In retrospect the experience explains a lot about her L322 = Hayabusa (or maybe cruise missile) driving style. No wonder the thing broke up on her. As the original laid-back-Larry who goes with the flow it irritates her no end that my normal road time over distance is as quick, or quicker, than hers. Motorways being different as she still figures blondes get to talk their way out of speeding tickets! 120 mph on a GSXR 1100 was pushing the envelope tho'.
