No worries, there are good discussions!
Yea, Hamilton/Rosberg was a pretty low intensity crash as compared to a car landing on someone's head All that said, this particulat walk off was pretty sad. It's a competitive sport (as all sports are), but you have to expect better from adults. And he had time to think about it as he walked back too
I can't recall specific instances, but I know Vettel checked on Norris in that crash in qualifying from a few months ago. And look up the Senna/Comas incident (Belgian GP, again). Comas' foot was still on the accelerator even though he was unconscious when Senna stopped to check on him. We need to expect better, ideally.
