“They should stay off of modern paved roads”.
I agree, Moonman62! You can’t have it “both ways”. You can’t refuse to use the reflective orange triangle because it is “modern” and sinful and then insist you can use public roads. A person can have all the religious beliefs they want but those beliefs STOP when it endangers me or my family. Granted, a car can do better than the buggy/occupants/horse BUT there is still a risk to the driver of the automobile (depending on size/speed/etc). This sect of Amish can choose to walk or hire someone to transport them. Or, they can stay at home. IMHO.
