1. An information processing system, comprising:
processing circuitry;
a first storage; and
a second storage, wherein
the processing circuitry is configured to
store a same total driving distance of a vehicle in the first storage and the second storage,
compare the total driving distance stored in the first storage with the total driving distance stored in the second storage,
determine that one of the first storage and the second storage has reached end-of-life when the total driving distance stored in the first storage and the total driving distance stored in the second storage do not agree with each other and the total driving distance stored in the first storage and the total driving distance stored in the second storage are not a predetermined initial value of 0, and
overwrite the total driving distance stored in the second storage with the total driving distance stored in the first storage without determining that the first storage and the second storage have reached end-of-life when the total driving distance stored in the first storage and the total driving distance stored in the second storage do not agree with each other and the total driving distance stored in the second storage is the predetermined initial value.
