You act like an ass driving these things, and there are severe consequences which follow. It's a shame the driver had to realise it only in the final few seconds of their life, but this profession can be very unforgiving. If this was, in fact, a rookie driver, then their company's training programme and/or driver training very clearly failed them.
Oh.. and did it appear to anyone else that he may have been trying to chase after the pickup truck?
I also noticed
this video, which is worth a look. Some of the accidents shown in the video weren't likely to be fatal at all, and not all of them are accidents in the US, as the video would seem to imply.. one clearly involved Canadian trucks (though I suppose it's possible it could've happened in the US), two are obviously in Europe (one shows a car wedged under a European curtainside van), and one shows a DAF cabover (at approx 1:36), which isn't a brand sold in North America (DAF is a Dutch brand owned by PACCAR)... hard to say where that one was from.. the truck is either a 6x4 or 6x2 tractor, which could place it just about anywhere in the world.. South America, southern Africa, Australia/New Zealand, etc. Looking again.. venturing a guess, I'd say there's a good chance it wasn't in mainland Europe anywhere, but who knows?'
edit: Found that same image
here. It was in Australia.
