Why we need cars
Unfortunately, we don’t live in that ideal world. If you live outside Dublin it is virtually impossible to get around without the use of your own mechanised transport. Bus stops are often miles from homes, and travel at irregular times.
Your destination may also be miles from your final bus stop. I also suspect that many of the “outsiders” she refers to who don’t or can’t drive benefit from the use of friends’, relatives’, or neighbours’ cars.
