I have been trying a lot of times this evening to take over in the rally training step18. But this is difficult for me.
Is there any place where i can see a demo of someone achieving this?

The few times I manage to take over, the car behind me bumps me from behind. Which enrages me after 100 times...

Or any tip maybe?

The only tip I can give you is just don't bother with those lessons until the AI is updated.

Do you WANT to make it as PRO? If not you can pass the two others in T1 just by braking after the second one does. Usually I manage to pull it off and then pass the other somewere else. Good luck with it

Thanks. I realize these AI are indeed well dodgey. I will do with those not involving AI like slaloms and such :P
I did all the tracks slowly to get an idea now of the places.
Not too sure which track and car I'm gonna start to practise with now.
