1. A method comprising:
receiving, from a mobile device that is optically tethered to a vehicle for remote driver assistance, an estimate of a speed of the vehicle, an orientation of the vehicle, and a trajectory of the vehicle and parameters related to a user of the mobile device, the parameters including one or more of: an orientation of the user to the vehicle, an orientation of the user to the mobile device, a speed of the user, a duration of an orientation of the vehicle with respect to a center of a camera-viewed vehicle image on the mobile device, or a number of deviations from a center orientation for the vehicle in an augmented reality view on the mobile device;
determining a user engagement score based on the parameters;
causing to present, via the mobile device, instructions for the user related to the parameters to prevent disengaging optical tethering and remote control of the vehicle with the mobile device as a function of the user engagement score, wherein the number of deviations with respect to center of the camera-viewed vehicle image includes one or more of:
a calculation of deviation based on a plurality of perimeter windows surrounding the camera-viewed vehicle image displayed on the mobile device, each window of the plurality of perimeter windows representative of a concentric magnitude of deviation;
a calculation of a magnitude of deviation from the camera-viewed vehicle image to center; or
a calculation of deviations over a predetermined period of time;
comparing the estimate of the speed, orientation, and trajectory received from the vehicle with a measured speed determined by one or more vehicle sensors; and
preventing vehicle motion based on a threshold difference from the comparison being exceeded.
