L to R: Vladimir Titov (hidden, has just shut off), Christophe Gilbert, Roberto Pennisi.
Here the late stage of blocking by Pennisi against Gilbert can be seen. The situation here is legal, (to my humble opinion) since Pennisi has advanced ahead by a quarter of a lap. A few laps earlier Pennisi's left arm was already locking Gilbert, however. This was repeated every time Pennisi had overtaken, and he got warned every other time, for an inevitable DQ at the sixth overtake.
