You have taken my comment totally out of context. I hope some see what I was saying. This is actually the last im gonna bother posting on this subject. I am not even going to bother answering about 80k, 200k incomes or any of that.

There is many things that are taken into account when fines are considered. They just arent plucked out of the air, there is attitude of defendant, previous record, severity of fine, failing to appear, co-operating with police etc... Thus if on the same day 2 people with identical offences and backgrounds where fined and one got a substantially higher fine than the other then it could be challenged.... hence the reading of the defendants circumstances by your solicitor when the fine is read out.

Thrush as said for £30 or whatever an mot costs book it and be safer or run the risk of getting done. If you have an mot its end of discussion.
