So you know when you're driving in heavy traffic at between 5 to 15 mph? When you lift off the gas you then get engine braking and when you try to reapply even a tiniest bit of gas you then get a lurch forward. That's what I'm referring to when I say jerky.
I find many manual cars can be like that... I also find most of my friends can drive the very same ones buttery smooth (except Matt, who is a bit special).
It's not the car - It's just getting the feel for the clutch/throttle balance and control. Took me a couple of weeks to get my own Octy right, especially as it has no throttle cable. Now, I drive it so well now I could almost say "Like a Bowss" every time I change gear... but I haven't watched enough Car Throttle videos to qualify for that, yet!
I'm sure 1st is long compared to a diesel, in that I could rev all the way to 7k in 1st if I wanted, but I don't like the noise so tend to change up at 3k hence 1st gear then feels relatively short.
I could redline mine, but again it sounds horrid... unless I'm misbehaving.
A tip I've heard from numerous driver-instructy sources is to try and keep the revs below 2k, for good, safe, sensible, gentle, economic, smooth driving... seems to work for me when I'm not in Hoon mode.
Having come from driving automatic cars before, though, I'd actually
not want another automatic again if I had the choice.
