Seems like more and more teams are using team orders lately. Jenson Button revealed he had to let Trulli pass in the Italian grand prix.
"... We didn't change anything on the car, it was just really big understeer, and I was losing out at the Lesmos and Parabolica to Jarno. So I thought I've got to let him past, because he's going to lose so much time. Well actually I was ordered to let him past!"
