I try online with a friend on Hillclimb in USA, it don't work.
Then I try in quick play (offline) on Extreme-Khana at the airport in USA. I finished twelve and I have got the achievement.
This event is good, don't need to go very fast, DON'T USE THE BRAKES, just decelerate and take the turn in drifting. It doesn't matter if your car touch something.
I use the Honda CR-Z, cat. 1
Hope this help.
