Here's my attempt to demonstrate how I go for it. Hopefully it's not too hard to see, since I have to record my screen.

I position myself slightly to the right. As I drive, my car slowly turns to the left. after tapping x once or a few times I'm usually able to get into a good spot and fall. This has been the most consistent method for me. The positioning isn't very strict and I'm sure you'll develop a slightly different way to approach it.

Also, if you're accelerating too much into the wall, it's almost impossible to make. You need to drop your speed and tap into the wall.
