This has to be one of the scariest videos I have ever seen.
It looks like the driver was making a very foolish manoeuvre.
It was caught on film by a Polish truck driver (who was somewhat involved) and reported in Belgian news (for that is where it happened) back in August here and updated recently here including comments from the unfortunate (or maybe very fortunate) Focus Driver. You may want to use a translate tool if, like me, you aren't familiar with the Dutch language.
This picture graphically shows the immediate aftermath.
Good job it was a left-hand drive car.
The video has gone viral and I can't say I'm surprised.
