The Amish near me drive tractors to town with rubber tires.  There are also some Amish women/girls who work as waitresses at a couple of local restaurants that are Mennonite owned restaurants.  I even know that the owners (own both businesses) have supplied some of them with a car to drive to work.  Evidently, they can drive a car, if they don't own it & if it is required for their job.

Now I don't know for sure if these are Beachy Amish or not, but I know that we rarely see buggies in town anymore - we are much more likely to see a tractor with a truck bed trailor behind it.  In fact, I was friends with an Amish woman *she has since moved away) who I met when we both went to work in a Mennonite nursing home and she would drive her tractor to work and once I went out to head to work & found it sitting in my driveway - she had brought the trailor with her and knew I wouldn't mind if she parked it in my old driveway and then she walked the 3 blocks to work.  They also had a phone & electric in their home.  They never drove the tractor on Sunday, except when she had to work on Sundays.
