Democratic cars have fifteen seats, two steering wheels, and no headlights.
Democracies struggle with opposing factions within themselves. Politicians only focus on getting re-elected the next term, and don't plan for the country's real future.
Bureaucratic cars have four flat tires and never start when you need them the most.
Bureaucracies are terribly inefficient.
Communist cars all look the same and most don't work.
(Soviet) Communism tries to make everything the same (or at least on the outside), but the government gets lots of "profit" (the cars that actually work). Plus, in the real world, Soviet cars were of low quality.
When socialist cars break down, the mechanic takes parts from the newest models and puts them in the oldest clunkers.
Steal from the rich, give to the poor.
No two libertarian cars use the same parts, but they crumple like tin cans in a crash.
Libertarians advocate great personal freedoms (such as "no seat belts required").
Anarchist cars are like compact libertarian cars that don't start.
(Stereotypical) Anarchists want great freedoms, too, but some want to form small communities. These communities won't cooperate very well.
Democrat cars come in all colors, but they all have mediocre engines.
The Democratic Party (USA) is the party of minorities, and is more liberal than the republicans (most advocate a certain amount of socialist programs).
There are two types of Republican cars: the high-speed sports cars, and pickup trucks that break down every week.
The Republican Party (USA) wants to allow great inequality in wealth (either naturally or artificially). Then rich are the sports cars, and the poorer people are the pickup trucks. I thought of Ford's cars with this one (they've made some great cars but now their models are inferior to Toyota
).
Win by luck, lose by skill.
