If your criteria is "funding the government" this concept is wonderful.
BUT if your criteria is maximizing GDP of the nation, a guy earning $20/hr spending a lot of time looking for a parking place is no big deal, while a guy making $500k/year can just decide to park in an illegal spot, pay the fine, and the country will benefit from having his time spent doing something more productive than looking for a parking place.
hmmmm... “from each according ...”
Where have I heard that ?
