When was the last time you pivoted, willingly?

I've never seen a slow pivot. By definition pivots are fast. 

Abrupt. 

And swift. 

Otherwise you run the risk of hurting yourself.

And presumably others who have the unfortunate chance of being nearby. 

You've got to make a somewhat reasonable, calculated, and informed decision before deciding to change direction. 

Too slow and you're late to wherever it is you're going, if you make it there at all. 

You're much better of pivoting willingly, than being forced to do it at the last minute.
