Hello Rig'n'rollers
Driving a long time with RnR, I'm now looking deeper in the game to find some useful details.
1) Oxnard Warehouse
At the exit of Oxnard warehouse, you come directly to an Y where you have to choose very fast which direction you'll take (north or south)
I've found that when entering the warehouse by the left lane, you'll come out on the lane for North and if you are entering by the right lane, you'll come out on the lane for South.
2) Wheel Brake broken
The failure of the brake is not linked to your driving behavior. In fact, it's related to the mileage of your truck. Once you reach the "break point", the brake will fail.
Hope this will help some ^^
