Being you have a child.... and anything can happen... what would you do in case of emergency and need a car?
And there are the weather aspects. When weather is bad, what will you do?
As an example: an Aunty of mine, who has a child, and who does not drive nor has a car (but her Husband has a car), recently called us in a panic. Why? Her Husband had fallen and had a huge gash in his head and bleeding etc. We live near her.
She had already called the ambulance, but they don't let you ride along in it. She wanted to get to the hospital asap. And calling a Taxi, was a big chunk of change etc. So she called us, being she was in a panic and we were the closest family near her. So we drove her and stayed WITH her at the hospital... which took several hours. Then her child stayed with us.
Things happen.
Of which you cannot predict. Of which, a car is very handy.
But again, you said the costs of a car and its care taking is money.
So, you have to weigh, the scenarios.... of not having a car.
BEYOND, the daily regular routines and errands etc. And if/when your child starts to go to school... how will will you take him/her to school to drop off or pick her/him up? And if your child is sick.... how will you take her/him to the Doctor? A sick child, probably will not do well in a bus. So then a taxi? And that costs money too.
And you have to think about, the logistics of where your errands are that you need to do, your grocery shopping, the location of the Pediatrician, etc.
And as you said, the bus can be on strike.
If a person does not drive, and does not have a car.... as you said, it can put a strain on another person, with whom you ask them to take you places. That is another aspect of it.
For me, and having children, a car can be a life saver.
You don't have to use it everyday. Thus controlling gas spending.
And you need to shop around, for a reasonable priced car. New or used. AND there are "certified used cars" at reputable dealers.
And, it seems you live on a hill.
Can you, pedal up that hill with cargo/a child in the back?
Or pedal down that hill with cargo/a child in the back?
