MSFS2020 live traffic isnt actual live. In 2020 they changed to method to have timetables from source and sim just injected airplanes. Like FSLTL does. Im not familiar with the MSFS2024 live traffic yet, but i assume it is not actual live traffic. If it is, that may be the case with hovering aircraft. FR24 doesent show fluid motion of aircraft in the ground, only in the air.
