my thoughts also... knew a lot of guys that have hitches on the front so they can maneuver their car trailers and campers. Instead of trying to back up with them.
I use to flat tow my Jeep and the tow bar was a "V" shape so it pulled from the frame rails. to the best of my memory (which is pretty shot) I've never seen a vehicle in tow, that has one central attachment point.

 

Maybe for a bike rack?

If it were to tow the HHR behind a motorhome, it would have baseplates (tabs) coming out of the lower grille on the left and right; you would never use a front mounted receiver for towing the car.

Nice black grille...

 

..... Thats the mount for the snow blower.......porta potty.........bike rack.....weed eater.....
umbrella shade.....movie camera seat.......

 

I thought towing it did NOT rack-up miles ?

 

I thought it did, if it's getting towed on all 4 wheels? Not sure though...
