Wherever you drive, however you drive, there are always going to be people who complain about your driving. I experience this all the time, even from people who are quite horrific drivers themselves. I decided once that I'd try and find a "neutral" party to give me some tips to compare my driving to some kind of standard. Of course this would apply to those of us driving stick, or manual.
Well, I found one such site - http://www.interlog.com/~css/manualprimer.htm - and realised there might be others who felt the same way but were too ashamed to ask. I know, expeienced drivers hate asking such basic questions, but the itch is there... well, I hope this helps: some tips on driving manual shift.
If you know of better links, please comment!
