Oh my god, how did I miss this thread!? I totally live in Amish county and have a relevant opinion
If you don't live in an area with the Amish, you don't understand how awful it is to drive with the buggies on the road. Where I live, they have a black metal base with a grey covering. Yes, almost the exact colors best suited to blend into a nighttime environment. At least where I live they do have orange plates and lights. Even then, they're still a huge accident risk.
What often happens is that the buggy will be kinda sorta on the shoulder. The car behind the buggy will try to pass through the middle of the road, thinking he/she won't hit any cars in the other lane. Obviously, this doesn't always work out.
An underrated problem with buggies is their steel tires. When you ride behind them, you can literally see the road being ground up under them. PA has some of the worst roads in the country. Part of it is because we hire cheap (aka terrible) contractors. But still, you can't tell me this is all coincidence.
As for the whole "even though they're backwards and misguided, you still have to respect their beliefs" thing, I can assure you based on personal experience and the myriad of horror stories that line of thinking is 100% bullshit. Their society is essentially a cult. It's structured intentionally to make it difficult for people to leave. And if you try, they'll use the legal system to get you back. And if you're a non-Amish in a business relationship with them, be wary of the possibility that you'll be treated unfairly because you're an "outsider."
Fortunately, their society also has its comedic side. I've heard stories from a couple different people about Amish guys growing and smoking tons of pot. The ones who do are irrationally cavalier about it because they get away with being excluded from society in so many other ways. For instance - brace yourself to seethe with anger - they don't pay social security taxes. Culturally fostering ignorance, technological stagnation, and child-abuse has its perks I guess.
