One time I was driving in the rain in some traffic. At one point I had a semi on my right and a guard rail on the left, with no shoulder. I was trying to get past the truck, but I guess he didn't see me, or maybe was clueless. He starts moving into my lane and my only option was slam on the breaks and hope I didn't get rear ended.
More accurately, it was the only option that occurred to me. Maybe I could have speeded up to get ahead, or even honked. Whatev, I did what I did and got very lucky.
The car slowed way down in a perfect and straight line, and I could tell there was a ton of computer guidance keeping the car from sliding or getting sideways. You could feel the anti-lock brakes being applied in a custom way on each wheel.
I was scared as shit, but knew my sorry a$$ had been saved by technology.
