I made the point some months ago on why we followed this planning and development plan since WWII and some fools got their knickers in a twist and nit-picked details.The balance on Ireland's roads and streets is currently massively skewed towards motorists. Lot of folk on here neither see that reality nor understand the major negative consequences on Ireland's health, wealth, environment and society.
The simple fact is, that we followed the UK and the USA in how we developed our country since the 1950's. They had a somewhat valid if misguided reason for it, as they had very large automobile industries that employed millions. We had no such industry at that scale. We were then very much an Agrarian society.
So why did we copy that development model? No idea, but I guess people like the freedoms car give us.
But it killed the small towns and villages of rural Ireland as everyone wanted a one-off house on a road a few miles from a town, sure the car would get to where you needed to go....
.... and still, people don't see the issue with this in 2024.
