Yes, he made the decision to speed and you would hope he'd be fully aware of the consequences, however the severity of the punishment compared with the incident at hand in my eyes, and the majority of motoring enthusiasts would probably agree, shows that the current laws we have in place for motoring convictions are extremely harsh compared with those for more severe crimes.
This is why he has my sympathies - he did it and got caught, ok that's his "choice" - but to be made an example of due to the excess in speed without taking into account the other factors (mentioned multiple times by many in this thread) without considering the impact to his job and livelihood is disproportionate to the amount of van drivers I know who have managed to get away without a ban, and thus no job impact, for incidents I, and I suspect many others, would consider far more severe than what this guy has done.
