1. An information processing system comprising:
one or more vehicles; and
a server communicable with the one or more vehicles, wherein:
a vehicle of the one or more vehicles is configured to:
acquire an image obtained by imaging a road on which the vehicle is located;
receive positioning signals from a satellite positioning system; and
determine a position of the vehicle when the image was obtained based upon the positioning signals;
the vehicle or the server is configured to execute determination processing for determining a degree of difficulty in traveling on the road due to snow cover from the image including determining that the degree of difficulty in traveling on the road is lower when at least two of four detection targets are detected from the image than when no detection target is detected, the four detection targets including another vehicle traveling on the road, a road marking on the road, a tire trace on the road, and snow piled up beside the road;
the server is configured to:
store the degree of difficulty in traveling for each of one or more roads, and
provide information to a client by using the stored degree of difficulty in traveling for each of the one or more roads; and
the vehicle is configured to control driving of the vehicle based upon the degree of difficulty in traveling.
