1. A method to control an automatic driver assist system of a vehicle, the method comprising:
identifying, using control circuitry, a first condition in the vehicle;
in response to identifying the first condition in the vehicle, preventing, using the control circuitry, a device necessary for a function of the automatic driver assist system from inputting data into a controller of the automatic driver assist system by interrupting a data channel to the automatic driver assist system, such that the function of the automatic driver assist system is restricted and the device necessary for the function of the automatic driver assist system remains available for use by another system of the vehicle;
identifying a second condition in the vehicle by:
determining that a siren of the vehicle is activated; and
determining that the automatic driver assist system is inactivated; and
in response to identifying the second condition in the vehicle, reactivating the automatic driver assist system by allowing data from the device necessary for the function of the automatic driver assist system to be input into the controller of the automatic driver assist system via the data channel.
