Funny someone is clearly trolling here.
Nowhere in the report did it say the JB/LH incident was JB's fault and yet someone could just state that as fact. Anyone with a right mind will see that the stewards verdict is that both drivers didn't have enough information at that moment to avoid the incident and hence nobody is held responsible, i.e. no one is at fault.
Also anyone with a right mind will not use this particular incident to comment on LH's recent driving. I do see one doing that in this thread, making a fast-slow-lane analogy, which I agree is completely wrong. But other than that I think it is the other incidents people are commenting on. So, don't get too excited, please.
On topic, I am not from the Lauda days so I'd rather not comment on his words or his credibility. As for Hamilton, I regard his driving very highly, but I agree lately he's been involved in quite a number of incidents / accidents which have raised a lot of attention. I don't think his driving changed too much - he was always very aggressive - he's just trying to put up a fight and maybe recently luck was not on his side and 10 gambles out of 10 didn't pay off. In some incidents he was maybe taking too much risk, in others he was more innocent, but in truth my hero Kobayashi is probably doing the same only that the latter had more luck (or maybe a tad more skill since he's my hero

). So I don't agree this is a trend developing like he's gonna turn into a car-ramming maniac.
