This one is a bitch, because even if you pile up all cars without every activating your crashbreaker, they still hit each other enough to burst into flames. Choose Pile Up Windrush & 1st with any car you fell comfortable with. Ram into the first car and hope for the best. I found a good trick to position myself on the right side of the street and then make a left turn to hit the first car frontal.
Just keep at it and eventually you will get this. It took me over 20 tries but it is not impossible. You just need the right amount of skill and luck.
