The world’s most expensive helmet?
Felipe Massa suffered an accident during the Hungarian GP in July 2009, when part of the rear suspension of Rubens Barrichello’s car came loose on the track, bounced, and hit Massa’s helmet.
At first glance, the piece of metal measuring 5 cm in length and weighs less than a kilogram would seem harmless, but when one hits you as you are traveling at 230 km/h, it becomes deadly.
Fortunately he was wearing a Schuberth RF 1.7 bulletproof helmet, which undoubtedly saved his life.
The helmet reportedy cost USD30,000 (about RM100,000).
However, since the projectile hit part of the visor, arguably the weakest component of the helmet he was still hurt:

I wonder, do they also ensure Formula 1 car mats are also bulletproof???
