This is an issue that comes up from time to time in various Amish settlements and I can see both sides of the issue. For newbies here I'll break it down:
CENTRAL ISSUE: The Old Order Amish don't own automobiles, but as their culture has become less insular and agrarian they have an increasing need for speed, whether that's running into town to get lumber, going to the doctor, or even the grocery. On something like the latter, this is partly a societal change, As more local Mom & Pop grocery stores get squashed by the Wal-Mart's of the world, small groceries get pushed away from "horse and buggy country", requiring an Amish person to either travel long distance by horse-drawn buggy or to hire a non-Amish driver, or taxi, to transport them. No, not the classic rude New York checker cab with a meter, but locals who just sort of hang out their shingle and offer to transport Amish for a fee in their cars. There are non-Amish people who make it their full-time jobs transporting the Amish in the larger settlements. Occasionally, the state sticks its nose in this business by requiring additional insurance, licensing, etc for the drivers and that is what is happening now in Pennsylvania.
CONS: It's more government when we need less (please don't make assumptions about my political views, you'd probably be wrong:), more fees, more regulations
PROS: I have personally seen a lot of non-Amish drivers charge exorbitant fees for their services. The hope is that the free-market would sort of sort this out on its own and that lower-priced reasonable drivers would win the Amish business, but that is not always the case.
SOLUTIONS: What do you think? I don't think a nice neighbor who just offers to transport an Amish person into town maybe in exchange for some gas money needs to be regulated,but maybe there some "mild" regulation and registration of the full-time Amish taxis. What do you think?
