I know you're going to hate me for this...

The example that's been mentioned is overtaking.
Imagine what you would do in a manual car...

Check the mirrors - is there a gap?
Life saver - is there really a gap?
Is the gap big enough to overtake in 6th? (lets assume not)
Drop down to 5th (or 4th)
recheck the mirrors and life saver
indicate
accelerate
pull out.

Now - imagine the same thing in the I-Shift. And imagine what the I-Shift is doing...
check the mirrors. I-Shift happily asleep in 6th
Life saver. I-Shift still asleep
Is the gap big enough. I-Shift still asleep
... (nothing here, as you haven't touched the box). So I-Shift still asleep
recheck the mirrrors and life saver. I-Shift - you've guessed it - asleep
indicate. Nope, I-Shift still snoozing
accelerate. ***!

Argh! blimey, best change down a gear or two!
pull out.

My point is - in a manual, you've pre-selected the right gear before you've mashed the throttle.
In an I-Shift, the first time it knows it's expected to do something is when you squish the loud pedal to the floor.

Now, bearing in mind that I still haven't driven an I-Shift, I can't comment on how long it takes to change down.

But I do know from experience of driving a DSG equiped TT (Audi's fantastic version of I-Shift), that even with twin clutches and all the pre-emptive gear selection of that box, it can feel like ages before it sorts itself out.

But (on the TT at least), the key word was 'feel'.

With the aid of a willing friend (who owned a manual TT), and a stopwatch which we shared, the actual time taken to go from 6th to 4th (worst case for the TT) was within tenths of a second of the best time he could do the same with a manual box.

But because with a manual box you are a lot more involved - press clutch, select gear, blip revs, let clutch out - it felt a lot quicker than with the DSG (driver involvement = press accelerator).

just my 2p

But my tip for today - when looking to overtake something, pre select the lower gear using the paddles, and get yourself sorted out in the same way as you would with a manual box

Hope that helps - and please don't hate me!
