The trick is to "blast brake", rather than drifting, you just tap the brakes twice, rather than hitting a wall! Also considering that I haven't used the other mines in the course I think it's entirely possible, it might just take a long time to pull off
I pulled it off after 9 days! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-96QZ9Uosry8.html Now I think I'm confident that I can pull off a 19:XX for the first lap, and a 17:XX for at least one of the other laps.
