First of all, if you mess up a mechanic, quit out to the main menu. When you go back in, you'll restart the scene. You'll probably have learned it early in the game already. (Kaine614 noted in the comments that after an update, you can use Game Rewind to redo misses. Thanks for the info!!
)
The last steering mechanic is missable, as stated elsewhere. As an FYI, when you get there, you're probably going to want to do this and then restart the finale.
Yes. The whole finale.
That's why I'm not going to put this in a spoiler. When you get to the part when you have to choose between Colt and Forsett, press
for Colt. Then follow the video below.
This is the video of when i got the achievement. You'll notice that I restarted. (IF YOU MISS, MAKE SURE YOU PRESS
TO RETRY. It gives you a few chances before it gives you the chance to skip. Don't skip.) I trimmed the video. I actually restarted around 7-8 times. You can too, so don't stress about having to do it right the first time. If you've done the other mechanics, this will pop immediately when you finish this last one.
Hope this helps!
