I was, like others thinking about the achievement was glitched, but I found the way to unlock it:
- First you have to play against the IA, I couldnt get it with 2 controllers.
- And the most important thing I see, is that you have to be ABOVE the speed so you dont take damage when you finish the race. I put a video where I show you how I get this achievement, and C4 and The Destroyer
