INFORMATION PROVIDING SYSTEM AND VEHICLE

An information providing system includes a plurality of vehicles, and a server configured to communicate with the plurality of vehicles. A vehicle-side controller of each of a plurality of first vehicles of the plurality of vehicles determines whether or not an act detected by an act detector is an abnormal act that meets a predetermined condition, and, when the vehicle-side controller determines that the act is the abnormal act, the vehicle-side controller transmits, to the server, abnormal act occurrence information including a position of each first vehicle detected by a position detector. A server-side controller collects the occurrence information transmitted from the first vehicles as collected information, and transmits the collected information to a second vehicle of the plurality of vehicles to notify a user of the second vehicle of the collected information.
