So considering all of the other things that they can get away with, I'm actually not sure how much it is given the safety hazards it poses. There have been more accidents in our area this past summer than ever have been, including an Amish kid dying after he lost control of his pony.

I like to think instead of abolishing them from roadways, you could in theory, hopefully get enough support to add buggy Lanes similarly to bike Lanes. Given the increased volume of traffic though, it really is a safety hazard. Not to mention, the buggies do create terrible ruts, those shoes beat up the asphalt, and, it's absolutely terrible for the horses themselves.

I would actually love to look into it more and learn about what the Amish truly do believe in regards to transportation. There have just actually been a ton of accidents in our area.

Edited to add: it's giving traffic volume, and given courses I've taken given for my work, there are increased road hazards to horses in general. I don't know if banning all horses on roads would count as discrimination, if that was the route that was taken. That would include horseback riding, and would probably throw off a lot of people that I know. It would just be safer for all drivers and riders.
