longer cord around or...

longer cable round or flat, useful if you are going to drive with the obd2 then you can give this easier to the co-driver can this co-driver at the moment that the fault occurs, div measurements immediately capture freeze and store, or if you are alone on the passenger seat and lay on a wide empty road without oncoming traffic or other traffic!!![ b.eg on a wide country road or on an empty industrial site with a slanting eye to store the data, also if you are under the hood you can use the longer cable to the OBD reader in plain sight with you, especially when driving div actuators so you can hear them working or not working while driving and you do not always have to go back into the car super easy if you are in a narrow garage
