I tried it in a off road condition, loose gravel with rocks. I think the DSC(not sure if that's what it called) is working very well. What it does is that it will stop the car for you on a down hill road. If you touch the accelerator a bit, it will decrease the brake force. Thus, not necessary means accelerating. Thus, this creates a situation where you can control your car a lot more than using the brakes and accelerator together. The noisy sounds horrible, but it just the normal ABS sound without the high pitch tires sound~ 2 penny~
