Re: Paradigm shift
It depends on how good public transportation is. SInce moving to Europe three years ago we don't have a car anymore, but public public transit in Barcleona is quite good.
Also we have several choices for car rental. The only thing I miss is the spontaniety of driving out of the city without previous planning. But we save a lot of money and the hassle of caring for the car.
I only wish that Car2Go or DriveNow were available here. Car2Go is now operating in Madrid so I hope they open up here soon.
