my brother did lose his licence for 17 days after being caught doing 105 MPH on the M6, he claimed he needed the car to keep his job and the employer was also a witness to varify this fact, it was the 17 day sentance that the employer was willing to give him to make it a "punishment" as well as not to deprive him of his livlyhood, in short they will listen to personal reasons, though from now on I would stick to the 70MPH speed limit on the motorway,
Wish you the best of luck with your court case, hope all goes well for you
