<description>
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
