A car race not an arms race

The Guardian notes (hat top North Korea Economy Watch) that the ambassadors of North and South Korea in London both have equally flash limousines. Though I'd add that while the number plate of the South Korean ambassador's car (ROK1) makes sense, the number plate of the North Korean ambassador's car (PRK1D) is far too close to Prick 1 for he to have been given useful advice of English colloquialisms.
