This is a partial quote from an article about today's race;


"The FIA, the series governing body, refused a request to allow the teams using Michelins to change to a fresh set of tires, and wouldn't even consider placing a chicane in the final turn to slow the speeds.

After a lengthy morning meeting, nine of the 10 teams said they would only compete if the chicane was put in place. Ferrari, which fields cars for Schumacher and Rubens Barrichello, was the only team to refuse the chicane.

All 20 cars lined up on the starting grid even without the chicane in place. But, after the warmup lap, the 14 cars on Michelin tires all pulled into the garage and parked in protest.

"It was very clear that we were unsafe today and we couldn't race," pole sitter Jarno Trulli said. "I'm really sorry for the USA fans."


I understand what the problem was , but what is a "chicane" ?
