Are you being obtuse? English is the most commonly spoken language in the world and US culture is extremely popular worldwide.

Evangelicals are an almost entirely US phenomenon. In the rest of the world, Protestant countries like Germany and the UK are more liberal than Catholic countries like Ireland and Italy. For example, Italy “legalised” abortion in 1978 but the vast majority of gynaecologists refuse to perform them on religious grounds. Ireland didn’t legalise until… 2019!

They didn’t assume most people are US-based. They assumed the DMV would be the most widely recognised and understood example to use.

I think people in the future will look back on how we raise livestock today as barbaric.

The Real Engineering video used as an example here is excellent.
