There is a hero in Argentina. In the animated gif below, you'll see a white van stalled on the train tracks. With no time to spare, the passenger on the motorcycle pushes the van to safety and narrowly escapes being hit by the train himself.
When I stumbled across this gif, I didn't believe it. A little Googling reveals it's true. Here's the full length video from the Municipality of Tigre camera.
More than 330 cameras monitor the different points of Tigre which allow police to stop criminals, detect fires and accidents or take pictures of reckless drivers and heroes.
