 * can be caused by several reasons, such as:
 * - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
 * - the sensor cannot calculate the accuracy due to lack of variables, or
 * - there has been a vehicle bus (e.g. CAN bus) error.
 * In all 3 cases above, the reported steering wheel angle value may be valid and used by the application.
 * 
 * If a steering wheel angle value is received and its confidence is set to 'outOfRange(126)',
