Playstation.Blog has posted an interview with Steve Hood, Chief Game Designer for F1 2011.
What improvements have been made to the AI?
This year a new system has been put in place to enable the AI to consider and act upon several things at once. Last year we had difficulties making the AI competitive on the hardest difficulty but this year… well… they are fast!
Have the long waits in the pits been fixed?
Yes, fixed! Entirely new pit system was implemented after we reviewed last years work.
