Again... reiterate...
The powerband issue is a problem in CERTAIN CARS.
Some cars more than others, but only certain cars are very problematic this way.
I mentioned this earlier in the thread...
Alpine VGT, the Mini Coopers, Autozam, Cappucinos, Copens.
And some others, yes.
But there are lots of cars where this isn't an issue at all, or isn't a big issue.
The other time AT comes a problem is like
@ryzno said:
AT is not always the best, as said before depending on the power curve.
My only problem with it is unlike a real AT, you can't get it to down shift when you want it to.
This is a BIG problem on hills, particularly in lower power cars.
Example: Fiat 500 '68 on Cote D'azur.
But again... how many cars need to shift down going up the hill at Cote D'azur??
Another issue:
If you're really bad at shifting... you're going to be faster in AT.
Not saying you shouldn't try shifting and practice, and get better at it. 💡
Just saying that in a nicely geared car, poor shifting is worse than AT. ^^
Also... if you manually shift but drive from sloppy corner to sloppy corner, you're going to be slower than someone who drives well, knows the lines, and corners properly using AT.
Edit:
Another time MT comes in handy is in light, floaty, spinny road cars.
Sometimes keeping it in a higher gear will stabilize the car.
But obviously if you're in a race car with loads of downforce, this probably doesn't come up.
