In parts of Europe speeding fines are adjusted to match the speeder’s salary.
Finland is best known for this system where the government uses their existing tax data to work out a fine that provides equal disincentive regardless of earnings (including benefits). This has seen rich Finns fined over $100,000 for exceeding the speed limit.
Variations of the Finnish system exists in Sweden, Denmark, Germany, Austria, the UK, France, and Switzerland, and the Swiss hold the record for the highest known speeding fine of €650,000 (AUD$1 million).
