Yeah, AI in A spec mode is still the same, they still park the car on corner exit if you are somehow near them. Seems like it's a script code PD used to let noob players pass easily and win races, but in this way they almost killed A-spec from D1. Arcade mode difficulty levels should be implemented even in Career mode.
Well, people wonder why these improvements are (still) limited to arcade mode, they wont give you credits for arcade races, In this way A-Spec mode is just something like a workplace, go grind for the money and than go have fun in arcade mode. It's an escamotage, but the Career mode should be always the core, the most enjoyable part of the game.
