Just watched on catch up.

Whilst interesting to see how the vehicles crumpled, it was totally unrealistic having the 'accident' happen on dirt causing massive swathes of dust to blur vision and reduce braking to a fraction of what even a wet road would have provided.

What should be stressed is just how unforgiving even a light-ish unladen truck is and how diifferent a real multiple accident is compared to the standard crash tests.

I do wonder if they’d anticipated the lady in the Prius being as ‘steady’ as she was and had to involve her somehow by running a van into her…

quite, in practice her Prius could easily been seen and avoided, hitting that was for dramatic effect, and the chap driving the big pick up would most likely have not hit anything at all had it not been for the dust.
