A stolen car or then necessity to carry it home without paying a tow truck. I call Mercedeses "Gypsies cars", they are preferred by them and also by some boulevard tourers that buy the car but do not even have the money to pay a tow truck.
Note that that manouver can be done only with a rear traction car.
BTW I did something similar a couple of years ago, my bro's car (a little Cytroen Saxo) had one rear wheel blocked, he stopped 5 km from home at night. I went there and it was something that couldn't be fixed on the spot, and the tyres were brand new (obviously...) so I changed the wheel with the spare wheel and went home literally dragging the tyre. After 3 kilometers the gum exploded and I went on on the flat tyre spreading sparks from the metal mesh of the tyre. Following day I disassembled the rear drum brake and found the the "soil" of a drum brake (the thing that make attriction against the metal drum) broke, slipped out and fit somewhere blocking the wheel, so I had to buy new brakes for the rear axel, new pumps for the brakes (the heat could have damaged them), purge the brakes oil, go to the tyre shop and mount an used tyre for the spare wheel (this for free, luckily).
Usually you do this thinghs because you don't have enough money to have the work done by someone else...
