 Peter Dumbreck , in response to his accident , initially blamed the height of the kerbs he had run on when his car became airborne , but Mercedes @-@ Benz responded by stating that blame did not lie with the circuit . The kerbs , as well as the entire Le Mans circuit , were all approved by the FIA . After the 2000 race the ACO and the French government did make modifications to the Route nationale 138 which forms the Mulsanne Straight , by decreasing the height of a hill by 7 @.@ 9 m ( 26 ft ) on the approach to the Mulsanne Corner where Webber had his warm @-@ up accident .
