We don't have a car.
However the ILs take us food shopping once a week and take us to family events/parties. Which is going to be a problem when baby
arrives as will not be enough room in the car. Also we go on holiday with ILs so again they take us. Am also reliant on them to take me to hospital when I go into labour (am 39 weeks pregnant now) but as they'll be looking after ds we'd be reliant on them anyway.
On the other hand we have no local train services (i.e. we could catch a bus into town to temple meads and get a train to london, but not any of the surrounding areas/villages where family are as no railway stations out here). Bus service is extremely expensive so mostly we walk.
The other thing is taking ds out for daytrips - most of the affordable places are in the middle of nowhere, so again no chance of getting there, or catching 2-3 buses and spending hours travelling.
We manage fine and I don't miss having a car. And if you are in London I expect you have much better/cheaper public transport than we do so will be much easier. Also you probably have a lot of local facilities there which makes things a lot easier.
Most things for us are easily walkable and you do get used to it quickly. Ds (5yo) is good at walking (though does moan sometimes) and it saves the expense, hassle of our cars constantly breaking down (which they all did) and tbh it often takes about the same time to walk once you take into account parking/traffic jams etc.
We have a lot of cycle tracks where we are which makes walking a lot more pleasant. I work within walking distance and ds school is same distance away.
I'd rather have the money than the car tbh. One thing though I would always keep cash in the house for an emergency taxi ride.
The main points I find can be a problem are
- food shopping - but is always internet shopping
2)emergencies - keep cash in the house
3)holidays - plan your holidays round public transport, e.g. where is accessible by train
4)visiting family - depends on where they are as to what you can do.
