I believe there has to be a certain amount of reality in driving simulators.
The better the simulator. The closer you drive in a realistic manner. The closer to reality.
Yes absolutely no doubt.
Thanks Pete for making these points.
This is entirely what sustains my interest in Grand Prix Legends.
The racing history and amazing art is icing on the cake.
The pics are from Piero Taruffi's The Technique of Motor Racing
When you read all the other books, they all refer to this one.
It is often noted the fastest way thru a flat 90deg turn is on the line that coincides with the largest arc that begins on the outside edge of the track, touches the inside edge at the geometric apex, and exits touching the outside edge again.
Taruffi demonstrates this approach results in slower lap times because time gained in the corners will be lost on the straights.
Faster lap times are the result of achieving maximum speed on straights.
To do this, you have to "cheat the corner," or as Graham Hill suggests, turn them into straights.
Notice point Z? Its past the geometric apex.
Anyway...here's the drawing where its all pretty much sewed up.
(From this point on, the discussion is about banked turns and other special cases).
Taruffi does not explain, when mentioning the importance of going off throttle, that going completely off throttle puts the diff into coast which "swings the rear out" and that, (as I understand), it is primarily diff and shock settings that effect this critical motion, (while springs and bars set the limits).
Notice he does emphasize simultaneous symmetrical countersteer to maintain slip angle and intended driving line.
