The Commonwealth of Spumeragne is a colossal, genial nation, ruled by Brave Knight with an even hand, and notable for its pith helmet sales, digital currency, and absence of drug laws. The compassionate, hard-working population of 3.948 billion Spumeragneans have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and look forward to their next free and open election, to be held on an as-yet unannounced date.

The relatively small government juggles the competing demands of Education, Administration, and Defense. It meets to discuss matters of state in the capital city of Radiator Springs. The average income tax rate is 15.6%, but much higher for the wealthy.

The strong Spumeragnean economy, worth 346 trillion tokens a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Book Publishing, Retail, and Basket Weaving. Average income is 87,605 tokens, and distributed extremely evenly, with little difference between the richest and poorest citizens.

It's often raining men (hallelujah) in Radiator Springs, public parks are littered with cigarette butts, sex offenders find themselves cut off from the ability to repeat their crimes, and grocery stores can be audibly identified by the giggling emerging from them. Crime, especially youth-related, is totally unknown. Spumeragne's national animal is the spider, which teeters on the brink of extinction due to widespread deforestation.

Spumeragne is ranked 96,766^th in the world and 189^th in Starlight for Most Developed, scoring 62.55 on the Human Development Index.
