I live in Israel in a city called Modiin and use public transportion to visit client offices out of town.
The public transportation by train to Tel Aviv, Hertzelia and Haifa is great, but anything else is somewhere between terrible and nonexistent. In the past year I use Waze Carpool and Moovit ( https://www.moovitapp.com/ , both developed and beta tested/dog-fooded in Israel) to get to those "unreachable" destinations at random schedules. A few times the results have been amazingly positive - being able to carpool with someone that lives just next to me and by chance needs to arrive exactly to my destination at the same time - and for the fraction of the price or the hassle of any other transportation method!
In fact - two of these drivers told me their family have gone down from two cars to a single car since using Waze Carpool, Moovit and public transportation to commute on a daily basis - a surprising statement from people living in a suburb such as Modiin. Once I was carpooled by a driver that responded to my request within 5 minutes and spent at least extra 25 minutes just to pick me up from a random spot in Jeruslaem for a 35 minute journey leaving me at my doorstep - saving me at least an hour, and probably for less than I would have paid for a bus.
