1. An update system comprising an electronic control device configured to store an autonomous driving logic and a server, wherein
the server includes:
a storage unit configured to store, in association with each combination of a user ID that identifies a user and a position on a road, personal characteristic data that is a part of the autonomous driving logic based on driving of a user and driving result data that is a record of driving of a user;
a personal characteristic creating unit configured to create the personal characteristic data;
a similarity specifying unit configured to specify, for each target ID which is the user ID to be evaluated for similarity, a user ID associated with the personal characteristic data or the driving result data which is highly similar to the personal characteristic data or the driving result data associated with the target ID at a plurality of positions; and
an output unit configured to output the personal characteristic data created by the personal characteristic creating unit to the electronic control device,
in creation of a first personal characteristic data associated with a first user ID and a first position, if first driving result data which is the driving result data associated with the first user ID and the first position is present, the personal characteristic creating unit creates the first personal characteristic data using the first driving result data, and if the first driving result data is not present, the personal characteristic creating unit creates the first personal characteristic data using the driving result data or the personal characteristic data associated with a user ID specified for the first user ID by the similarity specifying unit and the first position, and
the electronic control device includes a personal characteristic updating unit configured to update the autonomous driving logic using the first personal characteristic data created by the personal characteristic creating unit.
