You might only have access when the vehicle is moving on the road.<p>For instance, you might plant a roadside reader&#x2F;logger, and have an observer away from the road watching. The observer notes the time whenever a military vehicle goes by.<p>After you&#x27;ve logged a few military vehicles, you retrieve the logs, match them up to the observer&#x27;s time stamps, and now you&#x27;ve got a list of targets for your roadside RFID based bomb.
