Schumacher had every right to be angry.

They were under the yellow flag and the pace car was out ahead. They entered the tunnel and Michael was forced to weave his car to keep his Bridgestones heated up (and he was already at a disadvantage with Bridgestones) and brake hard intermittently to keep his brakes hot (braking late is Schumacher's trademark and it is how he is so fast). Juan Pablo ought to have known what Michael was up to and should have kept his distance.

Instead, Juan Pablo kept insisting on poking the nose of his Williams into tight spaces, although they were under a yellow flag and passing was not allowed. Eventually, the inevitable happened as the nose of the Williams went into the rear right side of the Ferrari, and thus the Ferrari went into the wall. Michael had absolutely done nothing to deserve crashing out.
