I find it annoying how they never go full throttle on the mulsanne straight, they always stop as 200mph or so, they only floor it on the test course, and even then they break at the corners and when they approach each other.
This is not true.
Run a race on Le Sarthe, or even just to the point where the AI finish going down the Mulsanne, then stop and play the replay. Select any AI car, then press the
'SQUARE' button and select "
Display", here you can see exactly how much throttle and brake the AI use, as well as gear, speed, RPMs, REV limiter warning light, and G-force. If you press the 'X' button to get the inside car view w/instrument panel you can also view the exact RPMs as well as turbo boost
(for cars with Turbos).
Believe me, I've spent a ridiculous amount of time putting the AI through countless miles and hours of
testing in order to better understand how they perform, and I promise you, they go full throttle down the Mulsanne, as they do throughout all the races. The difference is that they won't force the rev limiter to kick in, but make no mistake about it, they are using full throttle all the way to the edge of the rev limits.
It is also important to know that the AI use different types of tires for different types of races, and so for accurate comparisons you must be sure you are using the same car, same set-up, and same tires.
