Crashes vary a lot. I remember one time catching a loose cow that we'd tracked for 15 miles: our plan was for my pickup to wait in the tall weeds, then cut her into the pen as my brother pushed her - except all I did was spin wheels. I caught traction just as he gave up on me and bolted around her - then couldn't brake on the slippery weeds. I slowed enough to not hurt my brother but felt stupid for not locking 4WD! We did catch the cow tho, and drove both pickups home - but shop time followed.
I remember another where the other car turned left right in front of me. I knew my choices well, considered my possible guilt and would have swerved if I felt this was my fault even tho I knew the ditch was deep - but knowing it was not my fault in an instant, braked hard. Fortunately I slowed enough that no one was hurt, altho both vehicles were ruined.
Another time, on the way to dive training the next morning, a buck deer came out of the dark right in front of me. At 70 mph, I knew better than swerving so I braked and prepared for impact. Missed him! I don't know what he did as my eyes were closed for a second.
Another in a 55 mph zone on the edge of town, this idiot ran a stop sign - then stopped with half of his pickup in my lane, right in front of me! I did have room to brake, then after slowing - veer around him safely. It was his wreck, but I wanted to prevent if I could and managed to do so. He turned the other way, but I resisted the urge to U-turn and chase him down for an ass chewing.
The two times I've rolled vehicles didn't go as well, but each case is different. Usually I can weigh the options in a split second and choose the better one. I'll generally always vote for crashing over rolling.
We have no shortage of idiots who drive too fast on ice. I just hope they pass me safely enough...
