Like I said PB might have some issues, I know what I talking about-living in bumfuck part of Slovakia.
I do also know, that all public transport in EU si subsidised, so number of links, they routes and timetables are scheduled by local authorities, You need to take an action: write a letter to your council and inform them that there is this problem. They love solving problems if its for free: rerouting, or changing schedules cost almost nothing if so, and they can boast it in campaign. Of course is different in really rural areas, like in place, where I have my cabin- there are 2 buses per day, but its still manageble.
