Hey ,
this map is a bit out of the ordinary. While being fairly easy to finish when driving normally, there´s a trick which one should make use of to drive this map how it was intended. However, this trick is really far from being easy and that´s why this maps difficulty is set to "Expert".

While most of you should know the "Bugslide", which works on stadium and all TMS environments, coast holds another, but rather unknown kind of slide.

Short Explanation:
Bring the car into a sub 90° angle. Adjust angle by steering. The closer to 90°, the faster the slide is. Exit the slide by countersteering. If you exceed 90°, you slide out.
Important: DON´T BRAKE!! It´s NOT a bugslide!
Also, the slower the car, the easier the slide is to hold.

I recommend watching the GPS to see how the map is supposed to be driven. So have fun, try your best, and don´t get tilted too much, as the high-speed slide with drift transition really is fackin hard .
