A method of operating a predictive data cache includes receiving a request for telematics service from a telematics service requester, determining the subject matter of the request, querying a predictive data cache to determine if the predictive data cache includes a service response to the subject matter of the request and, if the predictive data cache includes the service response, then providing the service response to the requester and updating the predictive data cache using the subject matter of the request. The subject matter can include one or more of: an event description, an event period, or an event location based on the request.
