Lion smells something interesting in the back of tourist vehicle

The video shows how a young male lion finds the smell of something in the back of a tourist vehicle irresistible.
While on a self-drive safari in the Kruger National Park, we came across a pride of lions, slowly walking along one of the main roads in the park. With these lion sightings there are usually many cars around, filled with self-drive safari tourists, all wanting to see the king of the jungle roaming along the main road out in the wild. The lions were slowly walking along the tar road. Suddenly I saw one young male lion showing interest in one vehicle standing still, busy watching the other lions walking in front of them. The lion kept smelling at the back of the vehicle and it looked like the lion found the smell enticing. Whatever was in the back of that vehicle is debatable, but it sure had the young male lion’s full interest. Soon the owners of the vehicle realized what was going on behind them and they slowly drove off. Funny enough, the lion actually still went after it for another sniff before the vehicle eventually drove off.
