"Michael should have switched his brain on before trying that move," said Toyota's Ralf, who jinked at 180mph to make room for Schumacher at the chequered flag.
"He's crazy."
Earlier on the last lap, the 36-year-old Ferrari man - eyeing on extra point - muscled past teammate Rubens Barrichello at the tunnel chicane.
The Brazilian said: "I don't want to destabilise the team but I have spoken to Michael and boss Jean Todt (about it)."
Schumacher, though, was not in an apologetic mood.
"I would do it to anyone," he retorted.
"We don't give presents and I do not expect any either. I'm not here for a Sunday outing but to be on the edge."
