Is traction control and stability control important?

Impossible, 4x4 SUV with lockers and mud tires got stuck and overtaken by 4x2 jeepney? Baka naman nilagyan ng kadena gulong or naka lock differential yung jeepney or baka yung SUV open differential lang.

I believe the most likely reason would be that the jeepney driver simply knows where the rocky parts of the river are considering that it is part of his daily route, and the offroaders went straight to the soft mud.
