Do the crime pay the fine(or the time!)regardless of income.We all face the same punnishment for more serious crimes.
Someone who makes good coin may well have a very good vehicle which makes a given speed safer[for instance an Audi RS6 is safer at 160k's than a hotted up '85 corrolla!And an Abs equipped tourer is safer at that speed than my RF400] than some low paid labourer or student who has a cheap as machine that is not as safe at that given speed...Of course it all comes down to how the machine is operated as to how safe that speed really is but this is a generalisation
