 * This DE represents the absolute accuracy for a reported steering wheel angle value for a confidence level of 95 %.
 * 
 * The value shall be set to:
 * - `n (n > 0 and n < 126)` if the steering wheel angle accuracy is equal to or less than n x 1,5 degrees,
 * - `126` if the accuracy is out of range, i.e. greater than 187,5 degrees,
 * - `127` if the accuracy information is not available.
 * 
 * @note 1: The fact that a steering wheel angle value is received with confidence set to 'unavailable(127)'
 * 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)',
 * it means that the reported steering wheel angle value is not valid and therefore cannot be trusted.
 * Such value is not useful for the application.
