Improved AI times in Austria 2018-12-11

Thank you!!

thank you... Unfortunately I have to say that not all tracks are easily moddable, some circuits (like Austin, Sochi or Sepang) are really a problem 'cause it's nearly impossible to make the AI go faster in the corners where they are slower (they go off the line and lose even more time)... a way could be to speed up the AI in the corners where they are already fast but I don't like this way of working... Anyway I'll try to post something else in the future (Abu Dhabi seems workable)
