It's the most exciting part of the preflight cinematics! 😁

I love being in the dirt! :D

We could also let the MSFS AI steer our plane towards the runway👀

Just a note that this is a workaround and not a fix, it still will not work properly with the cinematic sequence but this is because we do not use the default MSFS parking brake system, and it is not possible to have the default parking brake system enabled and have custom parking brakes working. This is a sim issue and can't/won't be fixed.
