When a man is fornicating with a woman, and his thrust is so intense that his penis exits the vagina and is inserted into the woman's anus.
Man 1: Dude, I was banging Shelly too hard, and I accidentally got my dick in her pooper.
Man 2: Oh yeah, the high speed lane change. You gotta be careful not to cause wreckage.

The act of pulling ones penis out of a vagina then immediatly inserting it into the anus or vice versa. This process is then repeated over and over again.

When you try to pass a slow moving car by switching lanes only to find there is another car going slower, then you get back behind the previous car.
I had to do a Same Lane Shame Change after I tried passing the old lady in the POV then ended up behind a mini van.

Whilst having penetrative vaginal intercourse with a woman, usually with her on all fours in the "doggy" position, a man might suddenly transfer his penis from to her anus, without warning the woman of this sudden change. The woman's reaction is usually like that of other motorists when a driver swerves into another lan on the road without indicating: she honks loudly and attempts to stop.
"I was going away busily at this woman who was a bit loose, so I decided to take my chance, and changed lanes without indicating. You could have heard her yell in Sacramento, but boy, was she tighter there."

An extremely rapid lane change without looking, usually on a cell phone. This can be achieved in both city and highway traffic at any speed other than the posted speed limit.
While driving home from work, a truck colorado lane changed and came two inches from my passenger door almost running me off the road. (This shit happens on a daily basis. And no its not the damn californians)
