Burnout CRASH!

Firstly you need to unlock Blueclaw and 1st which is the last location in the game but the first event, you just need to have completed every road trip before that and have atleast 90 stars. This achievement is a bit tricky and requires a bit of luck but shouldnt take too long. Firstly start a pile up in the centre of the level and try your hardest to block all exits (this is mainly luck). Now just fall into one of the 2 visible holes either to your left or right and when you get taken back to the start take an immediate right into a small path which leads you to the next hole. Just crash in here and find your way into it. You may well lose some of your lives by here. Next go straight back into the centre and start playing as normal by stopping cars and blocking exits with them. Now just enter the 3rd and final hole (either left or right depending on what you did at the start). Finally all you need to do now is just survive until the end without losing all your lives.
Note: i used the "dust storm" car due to its high aftertouch which made making my way down holes and stopping traffic easier
