The Amish may ride in cars, busses and trains. There are "English" who make their living providing "taxi" service. They charge 50 cents per mile to drive folks to the store when they are too busy to catch the horse, hook it to the buggy and drive to town. They aren't supposed to fly, but under some circumstances they can be given permission though that is rare.
Whole busloads of elderly snowbirds descend on Pinecraft Florida in the fall and stay until spring.
They will take the bus from Pa to Wi and ship their household goods in a truck. Heck in Ohio they drive trucks and heavy equipment at their jobs at the pallet factories.
They are always scouting new land in Ohio too.

I saw elderly Amish tooling around Sarasota on big three wheel bicycles. They like to spend the winter there. They ain't stupid.
