 The 2005 United States Grand Prix was run with only six cars , after the Michelin tyres used by the other 14 cars proved unsafe for the circuit . A proposal involving the addition of a temporary <unk> to slow cars through the fastest corner of the circuit was suggested but rejected by Mosley . He stated his reasons for not agreeing to the <unk> : " Formula One is a dangerous activity and it would be most <unk> to make fundamental changes to a circuit without following tried and tested procedures . What happened was bad but can be put right . This is not true of a fatality . " He continued , " Formula One is a sport which <unk> . It is not entertainment disguised as sport . " Mosley gave three possible solutions for the Michelin runners : to use qualifying tyres but change them whenever necessary on safety grounds , to use a different tyre to be provided by Michelin or to run at reduced speed . These were all rejected by the Michelin @-@ <unk> teams . Paul <unk> , the then @-@ owner of the <unk> team who ran on Bridgestone tyres , was prepared to compromise to accommodate Michelin teams — even though a reduced field would guarantee his team much needed points — and was particularly vocal in his criticism and renewed his calls for Mosley to resign .
