The Amish allow their older children to "sow their oats" so to speak. After a set time they must choose if they will get baptized and join the church (community). Before that point they are allowed to do things they wouldn't normally be allowed to do. Including driving and drinking but hopefully not at the same time.

I remember this explained to me and have seen it almost first hand. My family was on the way back from a Florida vacation. We pulled into southern Chester County Sunday morning about 4am in a driving July rain storm. There was an open wagon being slowly pulled by a horse. The driver looked no older than 20 had a loose hold on the reigns and was stooped over and obviously out of it (probably drinking). One advantage under those circumstances, the horse probably knew the way home since the operator was probably totally unaware of where they were.

I tend to leave the Amish alone and let them take care of their own. Their transgressions into our world are usually far less offensive than our transgressions into their world (see West Nickel Mines shooting for example).

Most of them are (or were) Chumphumpers. Most of them refuse to wear masks and they believe the pandemic is a hoax. If they had TV in the house it would be tuned to Faux Noise, but of course they don't.

I might be wrong. But they’re “separate” from government things like school regulations.
