Whilst 118mph is a lot and will obviously warrant punishment, to say you're lucky you didnt kill someone is ridiculous. Without knowing when or where the offence was how can you say? Now i'm not defending going that fast and I never would; but if it was say 2am on an empty motorway the only person you're putting in danger is yourself. Therefore, its your decision really. Obviously if this was at a busier time then yes, you are putting others in danger and that's not so clever.
