[Other] - Pushback Optimization

:bullseye: What is your suggestion?
Further optimizations during the launch phase, including animations, movement paths, and sound effects

:hammer_and_wrench: How would it work in the game?
There seem to be some bugs in the delay of the pushback, but everything is going in a good direction. On this basis, some improvements can be made:
Asynchronous engine start during pushback: This has been mentioned before, the engines start in sequence, including asymmetric animations and asymmetric sound effects;
Delayed engine start time: The engine will only start after the real pushback, otherwise it will cause some safety threats to the apron personnel;
Apron personnel accompanying: At least two crews on both sides of the wing will follow the pushback until the tower gives taxi permission (someone has proposed to run pushback and taxi in steps);
Pushback to a more preferred position: For each parking position, there can be at least two AI-automatically selected positions for pushback, which can increase the efficiency of harbor taxiing, reduce interference with taxiing aircraft and increase the number of aircraft pushed out at the same time;
Mechanical inspection before taxiing: open/close the spoiler, and check after adding aileron animation in the future;
Flap opening: reduce the opening speed and add hydraulic sound effects.

:balance_scale: Why is this a good idea?
Better realism and improving taxi efficiency?
