a another thing that I loved in this game is the way the weather is managed, with on tracks like Le Mans, spa or nurb, you can have different area on the tracks with huge rain and some dry zones, it add so much realism, F1 sequel was the best IMO, GT7 go far beyond that
A another nice détail is the flag regulation, even on the menu carrer you have the flags working and flashing depending what's going on
finally the AI, and it's subjective, but since day one, I find them to be more clever and challenging, I think something have changed, they are no longer dumb as day one, maybe SOPHY is coming ?
