If so, ProTip - When you are not towing anything TAKE IT OFF. Then when you commute to work in your tow enabled trailer-less 4x4 and reverse into a space you don't stuff it into the front of peoples cars, like mine, while I am sitting in it.
That or learn how, perhaps, your 123819281928foot tow bar hanging off the back increases the overall length of your vehicle, you know - That's a distinct possibility when you put it on.
lol
sorry, no really it is very annoying when people do that.
I will not be removing the towbar from my landrover however, too many rusty bolts, besides, how else am I going to know when there's no more space behind my vehicle without the IAS (interference alert system) provided by the drop hitch and towball?

In all seriousness the only time I have ever nudged another vehicle was when some fool parked his car less than six inches from my rear bumper and the vehicle in front was a couple of feet away. It took ten minutes of opposite lock (not as exciting as it sounds) to get out. I was not impressed and the guy behinds car rocked about a bit. But common sense says don't park right up somebody arse, so I didn't loose any sleep over it.
