Amish lives are anything but anti-technological. In fact on my several visits with them, I have found them to be ingenious hackers and tinkers, the ultimate makers and do-it-yourselfers and surprisingly pro technology.
Some orders require the buggy to be an open carriage (so riders – teenagers, say – are not tempted with a private place to fool around); others will permit closed carriages. Some orders allow tractors on the farm, if the tractors have steel wheels; that way a tractor can’t be “cheated” to drive on the road like a car. Some groups allow farmers to power their combine or threshers with diesel engines, if the engine only drives the threshers but is not self-propelled, so the whole smoking, noisy contraption is pulled by horses. Some sects allow cars, if they are painted entirely black (no chrome) to ease the temptation to upgrade to the latest model.
When cars first appeared at the turn of last century the Amish noticed that drivers would leave the community to go shopping or sight-seeing in other towns, instead of shopping local and visiting friends, family or the sick on Sundays. Therefore the ban on unbridled mobility was aimed to make it hard to travel far, and to keep energy focused in the local community.
Turns out the Amish make a distinction between using something and owning it. The Old Order won’t own a pickup truck, but they will ride in one. They won’t get a license, purchase an automobile, pay insurance, and become dependent on the automobile and the industrial-car complex, but they will call a taxi.
