You have no idea how on the point you are. Especially for major accidents. Looking back it feels like it took hours because there are so many tiny details that stick out. Important stuff, unimportant stuff. Smells. Sounds. Voices. But all in all, it takes a few seconds at most to go from just another day to a really bad situation. Happened to me in 2004. Hit another vehicle that wasn't paying attention at an ungoverned merge. Still disturbs me to this day. It took perhaps a second from my reaisation that something was going to happen to it actually happening. A distance of maybe 10 meters.
