When I lived on the edge of Dublin you drove everywhere.Two cars per house is normal.Kids getting driven a little 10 mins walk from the house to school.That's why traffic is so shit for everyone.Public transport isnt great or efficient.You could be on the bus for over an hour off peak getting into town.
Now where I am walking to the shop,off-licence,chipper or dentist isn't a big ordeal. If I have to I can cheaply get to the city center if I wanna eat/drink out.
Everytime I get some elderly culchie coming up to Dublin to see some super amazing consultant I remember how much we have it good in Dublin.I've picked up oulwans in their 70s/80s coming up from Kerry/Mayo on the train to see specialists in Matter/Vincents.Ya don't wanna HAVE to have a car when you get old. They're expensive hobbies unless you've got a generous pension.
It's not for everyone but you need to try both to realise the difference.
