M1 Tragedy - How could it happen?

I’ve just been reading this story on the BBC Website.

Essentially, a Polish registered Volkswagen Passat drove the WRONG WAY up the M1 and collided at speed with a Jaguar carrying four people. The results shouldn’t be a surprise and tragically all we killed.

But what I find extraordinary is how the Polish driver (and I suggest he must be Polish) managed to get onto the M1 THE WRONG WAY. I mean that would mean driving the WRONG WAY around a round about, against the signs, and driving the wrong way down a slip road (again, with signs being backwards) before then driving down the motorway.

It just doesn’t seem possible to me how somebody could make so many mistakes. Yet, this appears to be the case.

More details are sure to follow.
