I wouldn't necessarily call it an easter egg as it happens where you have a customized plate and it transfers to the next car. Sometimes what will happen is the name of the car followed by a hyphen and numbers will be on the license plate if it doesnt have a custom plate.
More likely an outtake, i assume the car was supposed to land undamaged and drive past the camera at full speed
I also bet the update will be for BeamNG --- Post updated --- I need fox. I need to accidentally hit a fox in beam.
Roadkill in BeamNG would be so cool! Just driving in the D35 beast and accidentally smoke a deer. Or birds
