* This DE represents the absolute accuracy of a reported vehicle acceleration value with a confidence level of 95%.

* - `101` if the acceleration accuracy is out of range i.e. greater than 10 m/s<sup>2</sup>.
* - `102` if the data is unavailable.
*
* @note: The fact that an acceleration value is received with confidence set to 'unavailable(102)' 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 acceleration value may be valid and used by the application.
*
* @note: If an acceleration value is received and its confidence is set to `outOfRange(101)`, it means that the value is not valid and therefore cannot be trusted. Such value is not useful for the application.
