Craig Breen

[Mirek]

Breen's off was officially classsed as low speed. And the impact was side-on as the post went into the side window. None of this impact was anything like a shot from a howitzer.

Freak accident or not, I'd like to see it confirmed how the FIA saw it, and them clarify nothing can be done to prevent such a thing happening again.

Exactly. A shot from a pistol is 500J, that is 2000x less and an equivalent of a car moving by a speed of 2 km/h but you still need 20 mm thick glass to stop it. That is about 25 kg for a side window (glass alone, not a frame to hold it during a crash). For sure the bullet has a smaller cross section than a pole so the penetration ability will be lesser but for an idea about what energies we are talking about it is a good comparison I think.
