Damn! At least you have a newscast video of the aftermath. You're lucky to be ok... it looks like it took your entire front-end.
And yours was cherry red too.
That guy in the van was supragenius. Clearly he was pissed at the other car because he was blocking the passing lane. So when he goes aggro and passes him on the right, not only does he slow him down to a stop on a freeway. Not only does the additional car behind them turn on flashers to warn drivers behind. But he gets a fourth car to ignore the flashers, decide to drive up the barrier, only graze the third car, and pretty much impale the target car of his wrath.
Well done, gray van driver. Well done. My hat is off to you, sir.
