The smart miles box is the worst thing I have ever done.. I don't drive silly and the points you have deducted from the system go on ridiculous things such as acceleration and braking so if you brake to harsh (in their eyes) you have points deducted! Unless you drive ridiculously carefully then the box will be the Bain of your life as it takes points from you so often and is really difficult to regain again! There are too many sections where they can deduct your points from personally if I was ever to get another box I would find an insurance company that only went on the speed and not braking, acceleration, time of day etc
