This is a tiny modification to slow down the AI to realistic speeds on Rafa Sanchez' great track 'The Tajo Hillclimb'. For this to work you need to have the Donationware version of the track.
The AI cars are limited to speeds slightly above the allowed speed limits around the track and it also includes the AI to be speeding at three faster sections of the track in both directions.
To install this you have to replace the default ai_hints.ini in the folder:
It's advisable to make a backup of the default file.
How to use this:
In the current state of 'The Tajo Hillclimb' you need to select 'Quick Race' in Assetto Corsa to use the traffic layout with the AI traffic since this is the only way the AI is placed at grid spots around the track they can start from.
Other modes like 'Race Weekend' with practice or qualification sessions don't work since the AI doesn't manage to leave the pits.
With the selection of your position in the grid you can change your starting location on the track. I've set mine to random in order to be placed at a different spot each session.
Sadly the limited speed doesn't keep the AI from trying to overtake at places they shouldn't and can occansionally lead to AI crashing into oncoming traffic, be it another AI car or your car.
So I advise to disable damage.
Thanks to Michael Hornbuckle who had the initial idea to slow down the traffic.
I only took it a step further by adding locale limits instead of one global setting.
