Drifting on highway an hour ago.

[LeiZ]

Passing a car on an accelerating lane on my way back home. On my left side is grass land. I was at about 55mph, and his was at around 45. When I was approaching and ready to pass his car, this guy just didn't notice there's a car on his left, and he suddenly changed lane almost in a milli second.

When his car is almost hitting mine, I didn't even have time to horn so I made a fast steering to left, then the tricky thing happened. My X started drifting front with about 30 degrees angle to the left, then I steer to the right, the car still drifting front but 30 degrees angle to the right. It went back and forth 3 times before hitting straight back on the road. ALL the cars behind me were scared at least 300 feet away.

What happened? ABS was working? mud made the left wheels traction different and cause the drifting??? Freaked me out............

At least nobody hurts, nor cars..........
