Beware! Our sense of alertness isn't as good we think it is

Before you read on, watch the video. You may have seen it before but watch it still and you might be surprised. 

I was reading the chapter on the Illusion of Attention in Rolf Dobelli's The Art of Thinking Clearly and I am being warned. 

I admit that when I drive, I'm always distracted. I am always listening to music, looking at my phone and all. 

When all things are running as clockwork, where all vehicles are doing what they are expected to do, all will be fine.

But when something unexpected happens, and they do, I will not be able to react in time. 

There are no buts. Consider myself warned.
