-			Returns the vehicle body speed or velocity in a 3D vector, to get the speed in scalar value 
-			get the length of the return vector, the scalar value is in Godot units/seconds, if you 
-			assume 1.0 is a meter, then it is in meters/sec
-			Example:
-			    # vehicle is an instance of VehicleBody, 1.0 asumed as 1 meter:
-			    var speed_ms = vehicle.get_linear_velocity().length()
-				# Lets convert it to Km/h:
-				var speed_kms = speed_ms * 3.6   
+			Returns the VehicleBody's velocity vector. To get the absolute speed in scalar value, get the length of the return vector in pixels/second. Example:
