et pour répondre à une question posée plus haut, ce n'est pas obligé de rouler au dessus des limitations de vitesse : ce n'est pas une course mais une ballade en caisse à travers le monde :
"The 2006 Gumball 3000 rally (the Event" ) is NOT a race or a competition. You must NOT compete in any manner with other participants. You must NOT place any bets of any kind in relation to the Event. You must drive safely and with proper courtesy to all other participants and members of the public. "
