The blue paint.
Used at Paul Ricard, owned by Bernie if I remember correctly, or his company, or former company, not sure.
Either way, I wonder if it has to be blue, or if that is just for branding. Assuming it is a branding thing, amazing how much they are using at this money pit of a track.
Probably costs a lot of money per square unit applied, and makes someone very rich.
Aside from that fanboy thread worthy tidbit, I question it's use on the straight in the image. If it is that grippy, could it not cause a problem if someone ended up braking with one side or wheel of the car on it, snapping into a spin?
The things that a car can suddenly do when forced to brake on an unfriendly rumble strip can be hairy or straight up smashy.
Before I do anything I ask myself “Would an idiot do that?” And if the answer is yes, I do not do that thing. - Dwight Schrute
