Check your math - 0.8*75^2/2=2250J.
Quite an impact.

doubt it, that would have been the worst place, straight on at the visor would have been disastrous, might be bulletproof(doubt that too) but it ain't spring proof.

It could also have quite an aerodynamic advantage, getting rid of the imperfections in the airflow the cockpit and driver cause.
Giblet wrote:Saying that a metal face mask over the visor could be more dangerous to other cars is a negative way to look at it.
For the mask to come dislodged, the driver would have to be hit in the face with something very strong. It is about harm reduction. Massa with no broken face, vs a metal face mask on the track that just saved his face? They wouldn't come off willy nilly, just like visors don't.
Your argument is like saying airbags should be outlawed because of an occasional boken nose, and very few deaths even though they save countless lives.

That is a very very bad idea. Those can be accidentally set off by a mechanic in the pits, and for cripes sake it's an explosive! You cannot have them in a closed environment without an disproportionate increase in risk. What if it was tripped on the race track and you have a canopy either flying through the air or laying on the track around a blind corner. Why increase the risk for miniscule gain?!? It makes no sense. I'll go back to what I said in another thread, why put a FOD screen on a passenger jet engine and increase your risk of it coming loose and going into an engine to prevent a very small risk of a bird strike? With that screen over the engine during all times it is operating, you have increased the risk of something being ingested to takeoff and landing to whenever the engine is running. It makes absolutely no sense whatsoever. What if the canopy got stuck and the car was on fire? Since we are talking about the very rare happening here, that's a very valid thing to point out.

Could this be Proof that Barichello's car is not as well prepared as Button's?
