What a moment after the Qualy, when Hamilton received a legit Senna helmet of 1987, from the Senna family, during the on track interview. Really touching.
I think the big different between Hamilton and Senna pole record is that Senna, for the most part of his career anyway, didn't have the quickest car in the field (except 88, 89). Far, far, far more of Senna's pole laps were "wow, did he really do that!?!?" moments than what has been achieved by LH of late.
Not saying the Canada pole wasn't great because it was, but over the span of their careers I personally think LH has had it pretty easy in quali in comparison to when Senna set his times.
