To those who complained about the ending ... (SPOILERS)
You know the unrealistic way Mario was so happy and started to drive in total carelessness ... to his death. You know, recently, I drove during three hours in a very dangerous road, at night, and one of my car lights stopped working, the road was under construction and I could barely see in front of me, anyway, it was probably the longest and most stressful drive I've ever had (since then I never drive at night) ... I was so relieved when I came to the city that I bumped a car while I was parking.
The last turn of events, displayed in Clouzot's masterpiece, might not be 'realistic' plot-wise, but it's very true to life when you think about it. Hell, even La Fontaine said something about the irony of karma :
We often have the most to fear
From those we most despise;
Again, great risks a man may clear,
Who by the smallest dies.
