Value fwd_mps converts global velocity into a velocity vector which is rotated to cars local coordinate system (in this example x-axis). Then if key "ui_down" is pressed and the fwd_mps value is greater or equal to -1 (which seems to be very good spot and represents car still moving forward but nearly standing still) the car reverses (negative engine_force_value). If this condition isn't met (which means the car is moving forward) then the car brakes. Tested and working on Godot 3.1 Beta 3. Suggestions: In this case, if you want something more realistic, the -engine_force_value can be much lower because no car reverses in same speed as it goes forward but for the sake of demo project I left it as it is.

Godot demo projects
Each folder containing a project.godot file is a demo project meant to
be used with Godot Engine, the open source
2D and 3D game engine.
Important note
- The
masterbranch is compatible with the latest Godot version (currently 3.0). - Use the appropriate branch for your Godot version, such as the
2.1branch for Godot 2.1.x.
