When you're in Belgrade, or other parts of Europe where parking spots are very tight, don't park illegally! Your car can disappear in the blink of an eye.
We were driving around looking for a parking spot when we came around a corner to see the strangest thing I've ever seen. We were behind a flatbed truck that suddenly stopped. A guy jumped out of the passenger side and ran over to a car that was parked on the side of the street. Suddenly a small hoist thingy lifted off the truck and swung over, coming to a stop above the car. Four "tentacles" came snaking down and the guy who had come out of the truck quickly hooked them underneath the car. The car was then lifted right out of it's very tight parking spot, swung over and set on the flatbed, and driven away. The whole process took less than one minute! Here's a picture of a similar truck that was taken in Sofia, Bulgaria.
