In Britain, it is a lack of a regular or even non-existent public transport. With many rural bus routes taken off to save money. Without a car, a rural dweller has to rely on help from car owning neighbours, or ride a bicycle to the nearest town or village. Not much good if you are old or infirm.Another disadvantage, is poor or no mobile network, or internet access in some areas - though it is slowly improving due to the Government expansion of fibre broadband.In winter, or during heavy prolonged rain, many villages can be cut off by heavy snow, or flooding for days.But after all the moaning above, I live in a small village in Lancashire, England. We have an hourly bus between two cities (though it stops around teatime. I've got BT fibre broadband. My mobile works, but I hardly use it. And at the end of my cul-de-sac is a Spar village store. Also, my son (with a car) lives about 7 houses away. So I can recommend rural living.But you must plan ahead for the time old age and possible immobility causes problems.
