That's exactly how it happens. Overtaking in blind corners with fairly big vans (these things exceed 3 tons fully loaded and they're 6.6 meters long) and then ramming their vehicle back into the lane they're overtaking if they run out of room counting on the rest of the drivers to absorb their mistake.

And if that doesn't work then too bad for you...

The first time this happened it scared the crap out of me, now I'm more prepared and I will keep a very large truck in front of me on the most risky parts of the passage, they rarely try to overtake that combination, it's just too long.

Defensive driving gets a totally different meaning on those roads.
