1. A vehicle comprising:
an input device; a display; a rear vehicle speed dependent ideal distance maintaining implementer, wherein when a 1st current distance which is the current distance between said vehicle and a 1st vehicle which is the vehicle traveling in front of said vehicle is identified to be longer than a 1st current ideal distance, the current speed of said vehicle is increased and a speed increased message is provided in an audio and/or visual form, and when said 1st current distance is identified to be shorter than said 1st current ideal distance, the current speed of said vehicle is decreased and a speed decreased message is provided in an audio and/or visual form, wherein said 1st current ideal distance varies depending on the current speed of said vehicle; a front vehicle speed dependent ideal distance maintaining implementer, wherein when a 2nd current distance which is the current distance between said vehicle and a 2nd vehicle which is the vehicle traveling behind said vehicle is identified to be shorter than a 2nd current ideal distance, the current speed of said vehicle is increased and a speed increased message is provided in an audio and/or visual form, and when said 2nd current distance is identified to be longer than said 2nd current ideal distance, the current speed of said vehicle is decreased and a speed decreased message is provided in an audio and/or visual form, wherein said 2nd current ideal distance varies depending on the current speed of said vehicle; and an inter-vehicle middle point maintaining implementer, wherein an ideal middle point which indicates the ideal middle point location between said 1st vehicle and said 2nd vehicle is identified, when said vehicle is identified to be behind said ideal middle point, the current speed of said vehicle is increased and a speed increased message is provided in an audio and/or visual form, and when said vehicle is identified to be beyond said ideal middle point, the current speed of said vehicle is decreased and a speed decreased message is provided in an audio and/or visual form, and wherein said ideal middle point varies depending on the current speed of said vehicle. |
