Here's a sample of worn tires (hindi pa nga super pudpod yan) suddenly oversteering on a damp road:
The usual response of drivers when their car loses control is to stomp on the brakes. If I did that, the car would've continued to oversteer and I could've spun and hit the motorcycle driver on the other side of the road.
That's on a FWD car, if you have a RWD like a pickup or PPV, the propensity to oversteer is higher. My officemate before suffered the same conditions but wasn't as fortunate - his car oversteered, he overcorrected, hit a side rail, and then his car turned turtle and landed on the other side of the road. Thankfully he was okay but his car was totalled.
In comparison, understeering is easier to correct by simply letting go of the gas pedal and waiting for the car to regain its traction.
