Finland links speeding fines to income. I'd like to see something that get far broader application. That prevents the wealthy or huge corporations from seeing lawbreaking as a business cost, without destroying a small business or individual who commits the same crime.
Proposals like this are how you get the billionaire paying their chauffeur's $50 fines so they can get everywhere faster while sticking some small business owner in an industry with feast or famine years with a $50,000 ticket for having a slightly miscalibrated speedometer.
Creating new arbitrage opportunities benefits the powerful, not the weak.
