I find it fairly hard to tell when the cars are beyond their powerband with the new version... I don't have that problem IRL, but when my body isn't experiencing any forces, I find it pretty difficult. In addition to that, LFS doesn't even give you a dyno graph for the cars - which I think is ridiculous.
No one has even brought up the point of when you're nailing it out of a corner and you have a ridiculously loud car next to you, you can barely even hear your car.
I rarely get to the limiter in LFS but I find I'm over-revving the motor a fair bit of the time with the new version.
And while it's fairly realistic, I find it pretty annoying that most of the LFS cars seem to have tachos situated so that the needle is almost horizontal when you need to be looking at it, not like the good old 60s touring cars with tachos mounted on weird angles to make them as close to your eye's focus at critical points.
My car has a shift light, and with a street exhaust I think it's a necessity when you're racing. And it's worth 3/10ths down the quarter as well
