Solved the issue with 2 angular velocities. Decided to use just one, and make an additional check for RelativeTo property, where as if you try to steer, it will check if RelativeTo is World, and if its not, it is changed to world. Same with Throttle but reversed. This does not allow to Steer and Throttle at the same time but it works. Still, I don’t know how to add an additional key to seat.
