“I’d rather wait for the FIA to share the information from by themselves as perfectly as Alfa as to particularly what took place, when we establish a load situation. Are there standards by which we can examine all the vehicles rather? Would all the automobiles stand up to that or not?

“That’s something which has got to be thorough in reviewing ahead of we kind of guess at it. It would be I assume a minimal naive to say ours is various from any one else’s.”
