Actually I came across a web page which seemed to say something about that, but I can't understand how a car could be towed in such an asymmetrical fashion. Wouldn't a tow hook need to be in the center of the bumper?
If it is a disk in the bumper, which it seems to be, it may be radar device for measuring distance to the vehicle in front. I have a VW with the same thing. It's used by active cruise control to match the speed of the vehicle in front.
When I bought a car I asked the salesman what that little thing in this picture is (the thing on the front bumper that I circled in red). He said he didn't know what it was because it's not functional on cars sold in America, but that it was for some purpose required on cars sold in Europe. Can anyone tell me what it is?
Sorry this picture looks smaller here than when I found it online (not my car), but maybe you can tell what I'm talking about from the location on the bumper.
It's good in heavy traffic. You can be going quite quickly on the freeway when a traffic jam is up ahead. I can set the follow distance. My car just stays that distance whatever speed I've set. In 5 years it may have saved me a nose to tail bump. It can slam on the brakes if necessary. And it's good deal faster than my reaction time.
