Question 8: The birds' insecurities about Michelin tires at Indianapolis Circuit 13 led to the strike of all the 14 cars of seven teams.

After Schumacher of Toyota had a flat tire in practice, other teams using Michelin tires also found tire safety problems one after another. Then Michelin airlifted another batch of tires from France and found that the problem still existed. After that, seven teams using Michelin tires proposed to the FIA that they would not participate unless the rules of the competition were changed. After careful consideration, international cars suggest that teams using Michelin tires can change tires at the pit stop, or solve this problem through the speed limit of 13 corner. Seven teams using Michelin tires can ask teams using Bridgestone tires to speed limit at the same place. The FIA thinks this requirement is unfair to the teams using Bridgestone tires, so it doesn't agree.

Finally, although all the cars came to the venue before the race, after warming the rims, 14 cars drove into the pit under the leadership of Trulli. Under the rule that 12 cars will be cancelled, the FIA still let six cars finish the race. This decision made the FIA say no to Michelin!
