13. A method of operating a mobile milling machine having a cutting rotor accommodated in a rotor enclosure, the method comprising:
spraying a liquid within the rotor enclosure from a plurality of spray nozzles during a milling operation to mill a work surface;
determining a wetness of the work surface rearward of the cutting rotor after milling with a surface wetness sensor in cooperation with an electronic controller;
comparing the wetness of the work surface as determined after milling with an acceptable dryness level associated with the work surface, wherein the acceptable dryness level is based at least in part on a distance between the mobile milling machine and a second mobile machine; and
adjusting a spray quantity of the liquid if the wetness of the work surface as determined after milling exceeds the acceptable dryness level.
