I have total regard for others safety, especially ingrained as a motorcycle rider.
Some one rams me from behind, it is 99% likely their fault (or maybe the guy that punted them into me).
My vehicle gets slammed, I could be out my deductible if it turns in to a he said this, and I say that. At a minimum I am dealing with a couple weeks hassle of dealing with a body shop and insurance.
In the end, if someone truly gets hurt that fact that I left the ball in is not gonna make a difference....they hit the receiver and hitch in 4 more inches.
I'm gonna leave mine in, thank you.
