This mod is made upon request and is the opposite of my "fix ai repetitive going off-track" mod. Please note that this is not realistic and only for those who like to have some fun to have ai going off-track in all circuits at some corners.
Make backup and replace files accordingly.
You may adjust the value of the parameter as shown below in red in ai_vehicle_config.xml. The higher the value, the harder for ai to stay on-track and vise versa. A value of 1.0 is the default, i.e. no change for that circuit.
eg for texas
<laDistMin float="11.000000" />
<trackGlobalCurvatureModifier float="1.1" />
