This great feature has now come to AC and I think IMHO it should be in all racing games, the
HeliCorsa Radar App. It comes in so handy for knowing where everyone is around you without having to hit buttons to look back and see who is there and covers those all important blind spots with ease. GT5 had a scalable mini map which did the same job and made for much cleaner racing overall and HeliCorsa takes it one step further in that it flashes when someone is close to you and you can instantly notice it off to the side of the screen like an early warning system. I think of it as a kind of non-verbal spotter. If something like this is not in the game, could someone please suggest it?
