No, you first, be honest to yourself. I know you're capable of it.
He lost control of his car due to several factors, but the start of that chain reaction was the abrupt and unnecessary stopping that the original didn't anticipate.
You're telling me without the brake-check, the guy would have lost control on his own? What happens if the guy in front would just move over as soon as he's cleared of the car on the right without any abrupt actions? Wouldn't that be better for all? Instead of brake-check? Nah, can't be, gotta police the road. I weep for humanity, and Florida.
If you were driving that car in front, and you did the brake-check, and the guy went onto the other side of the road, have a head-on collision and someone died, you'd just drive on and in your mind saying "not my fault"... I get why you'd think that. But, you'll never do.
