In the Hummelverse, tanks rule the known world.
Tanks usually don't have family names as this tradition was abandoned over time, but some older ones still do.
There are three main types of tank names - fantasy names, trivial names, and nouns.
Major language groups and dialects
English and Russian are the most commonly spoken languages in the known world. As a written language, Tank Runes have mostly replaced other alphabets. A language that was widespread but is no longer spoken is Machine Language.
Culture and cultural heritage
Many cultural leftovers from the humans are still present among the vehicles. They use words and phrases like "face" or "brains" even though they make little sense to a contemporary tank. The cultural values of tanks vary greatly between the generations. Since most tanks don't live long, cultural traits die as quickly as they are re-invented. Even when they get passed down generations, it is usually only locally. Therefore, one will find many different sub-cultures when travelling through the land. Each of these sub-cultures have their own traditions, additionally to the more universal ones. While those are also subject to rapid change, they are perceived as persistent and imperative.
Common Etiquette rules
Most tanks are very mistrustful of others. (Of course there’s also gullible ones, but they tend not to live long.) It’s normal when someone acts downright gruff, especially towards strangers. While some things that would be seen as rude in our world are acceptable behaviour among tanks, the lines are drawn at threatening others or pointing one's cannon directly at someone when looking at / speaking to them.
Referring to someone by their name is reserved for tanks who are close to each other (friends, siblings, partners, ...) and may otherwise be seen as respectless. Instead, tanks address each other by their model designations, unless there is ambiguity, in which case nicknames are used.
Funerary and Memorial customs
Deceased teammates are usually not buried. Most of the time, their parts are salvaged to be used by teammates in need or sold.
Common Myths and Legends
Humans are known, but generally assumed to be all dead. Others believe they still live hidden somewhere. There are elaborate belief systems that involve mythical vehicles and factories. Not everyone believes in them, but their names and stories are widely known. Due to the lack of contemporary witnesses, historical facts and accounts are distorted and even outright replaced with fantasy stories.
Gender or biological sex like humans practiced it makes little sense to tanks and has been mostly abandoned. Sexual dimorphism is observed in animals still, which is probably the main reason why the concept of gender still exists at all in tank society. It lives on to a degree in the fact that tanks like to choose gendered pronouns for themselves; a tank's pronouns are indicated by a special symbol on their armour.
Relationships are common but usually discouraged. The concept of marriage exists, but is uncommon especially among younger generations.
