1. A computer-implemented method that, when executed by data processing hardware of a vehicle, causes the data processing hardware to perform operations comprising:
gathering sensor data;
calculating one or more groove detection confidence values with the sensor data using one or more groove detection modules;
evaluating the one or more groove detection confidence values using a road groove detection fusion module;
determining whether a road groove is detected;
communicating road groove data to an advanced driver-assistance system; and
adapting trajectory and steering controls of the vehicle.
