Well, maybe this is something worth discussing. It looks like the Mulsanne straight and chicanes have been repaved.

I wonder if this could have any impact on the racing in the future in terms of change in smoothness of the transitions between the straight and the chicanes, the crown, tire wear, and overall lap times. My guess is that it won't be a huge deal, but it is something new to wonder about.
