The week's pay was just an example to avoid using something involving percentages, which would have gotten too math-messy for a comment. I have no idea what the best percentages would work out to be.

In any event, what do we do -now- when people don't pay their citations? We'd still do that. This doesn't create a new system, nor change anything at all downstream of the citation. It is merely a new, more just and probably more effective, method of determining the fine -amount-. The rest stays the same.

Still just a citation with a fine, under a proportional system the fine is merely based on documented income (which, off the top of my head, could use either tax records, or the documentation required for public assistance, or the like) rather than some arbitrary, "one size fits none" amount.
