It appears largely this sim is a copy and paste regarding the flow of traffic and structure of AI routes, etc. To improve on this, it would be more immersive and possibly performance improving if certain parking spots are designed as a drive-through parking. This way the sim doesn’t have to place a push back crew at every spot and also improve problems where an airport actually has parking like this and the push back parking causes traffic jams and unintended collisions. This would be great for 3rd party developers to utilize or anyone who wishes to alter their own airports.
Yes I know, you can drive right through them, but that immediately kills the immersion right from the start of the sim. If you further make parking spots custom to the needs then this can be avoided and creates more possibilities for the GA world, the same as the airliner spots.
