Frankly a head-to-head collision between two cars at high speeds is the most unlikely of all scenarios, when it comes to accidents, and therefore is statistically irrelevant in any passive car safety considerations. Or in other words: If you try hard enough, you will find a scenario for every car, where survival is impossible.
So I fail to see the sense in that kind of crash tests. However, there was an article here in a car magazine some time ago about some lobby groups in the USA, which tried to promote big cars and thus support the US car makers by showing that smaller cars were unsafe.
I suppose those videos are connected to that but it's a very stupid strategy, if you ask me.
