Parking disputes are fuelling tensions between neighbours with reports of verbal confrontations, vandalism and even cars being keyed.
Earlier this week, Prime Time examined how parking shortages are causing stress for residents.
It comes as some new developments are being built with no parking options.
Dr Lorraine D'Arcy, a lecturer in sustainable transport at TU Dublin, told Behind the Story we have "normalised" the idea that people can park anywhere.
"We have normalised that you can park your car anywhere… then when a cost is associated with it, then it becomes really contentious."
Dr D’Arcy said multi-generational living also means houses could have several cars.
"You will see in certain suburbs where you have multi-generational living," she said, "the bigger houses that have more bedrooms, there are adult children living in those houses."
Forced into car ownership
Dr D’Arcy said we have also been "forced into car ownership" because of how our planning has taken shape - with information around travel based on work and school data.
She says for many people, a car is necessary to drive children to sport, with matches held across cities and counties.
Dr D’Arcy said she welcomes approaches that take a bigger overview.
"Bus Connects is one of the best projects that we’ve done, in my opinion, because it combines the radial and the orbital - we’re actually thinking of the trips that aren’t just in and out of the city, they’re thinking about how people are getting across the city," she said.
"But finally, they’re looking at the whole city - whereas before we might have prioritised a rail route into town."
Dr D’Arcy also reveals why certain bus routes have shelters and others do not.
