Secret Unicycles in beamng

Hello everyone! Today i wanted to make a video about interesting things about beamng, and then after finishing my video i seed something interesting, there is beamng unicycle, and to enable it you need to click Include auxiliary debug content, and at the props section you will see an unycicle, there is 3 options here, debug mesh and snowman, other is just unknown, and yes some people dosent know about this, even me, when i just clicked one button

 

the unicycle is the "vehicle" the game spawns when you press F to get out of your car

 

yes, but interesting thing that that there is 3 options to pick, and it kinda weird
