We just look at bus stops etc when deciding where to live/work
Dh takes the bus an metro to work, kids walk, cycle or bus to school (or sometimes get a lift from the nlaws, but we do just fine without that, except for getting a bit wetter if it is raining) and I walk or cycle to do my main job, then bus and metro to my other job, which is in the centre of Newcastle on match days anyway so a car would be useless.
Shopping is either online, Iceland (delivery) or I just take the bike traile or the bag on wheels. Occasionally get a taxi home from the shops.
Holidays by train, which can smetimes be a pita, but again I have no idea how I would drive, keep kids amused, have to stop for toilet breaks ver five minutes, get lost etc, without thinking it would have Ben better by train.
So, yeah, a car would be nice, if only so we could take the bikes further afield, and dh could spend less time commuting. But not the end of the world. Having a licence so we could hire a ca would be nice I suppose.
Public transport costs us £80 a month, which I think compares favourably with a car, and if the bus breaks we just catch another.
