An interesting question for both this crash and for Silverstone. Would the crash have still happened if both drivers were Max Verstappen? Would the crash have still happened if both drivers were Lewis Hamilton? I've thought about it for a while and come up with yes and maybe respectively.
I'm still baffled why Verstappen didn't take the exit run-off like he did earlier in the race. It just seemed like he had huge, obvious understeer and hitting the orange sausage with his left wheels was only ever going to be the best-case scenario - which was always going to bounce him towards the gravel whether there was a car next to him or not.
It just smacks of angry driving and a "Lewis is NOT getting this position" mindset (and Hamilton's tyre grade advantage would have meant that even if he'd got the spot it probably wouldn't have lasted the lap).
Incidentally, F1 has released 360 degree onboards from both cars...
The penalty is, I think, harsh, though he is obviously predominantly at fault - but it looks quite like the stewards are punishing him based on form. He's gone from routine wheel-banging and running cars off the road, to a 170mph crash (which was about 50:50, but easily avoidable for him), to driving over someone's skull in a ridiculously belligerent move. A grid drop and penalty points seems to be the stewards trying to stamp on his on-track behaviour before someone gets badly hurt.
