1. An information presentation device comprising a processor configured to:
select a preceding vehicle candidate that is a candidate to be followed by an own vehicle based on information about a surrounding vehicle around the own vehicle;
estimate an extended cruising range of the own vehicle obtained by a follow-up travel of the own vehicle traveling behind the preceding vehicle candidate; and
output, via an output device provided in the own vehicle, the extended cruising range as extension information of a cruising range of the own vehicle when the own vehicle follows the preceding vehicle candidate, wherein
the processor is further configured to
(i) calculate an estimated accuracy of the extended cruising range based on (a) a first confidence degree of a degree of reduction of an air resistance obtained by the follow-up travel of the own vehicle traveling behind the preceding vehicle candidate, the first confidence degree of the degree of reduction of the air resistance being determined from a manner in which information about the preceding vehicle candidate was obtained and a driving support level of the own vehicle, and (b) a second confidence degree of a continuable distance of the own vehicle performing the follow-up travel of following behind the preceding vehicle candidate, the second confidence degree of the continuable distance of the own vehicle performing the follow-up travel being determined from the manner in which the information about the preceding vehicle candidate was obtained and a reliability level of running environment information about a driving route of the own vehicle, and
ii) change an output mode of the extension information based on the estimated accuracy.
