Yes, I couldn’t have got to work without a car when I worked. I went for my interview by public transport and it took me an hour and a half to get there (bus goes all around the houses) and I had to get a taxi home because the bus got cancelled. Travelling by car its a 20 to 25 minute journey.
Balders, DH and I discussed reducing to one car when we were both retired. DH was a biker so had a stable of motorbikes. I said fine but I will choose the car, because we have very very different preferences, and I will have first call on it because you can always take a bike.....he thought about it and we kept two cars!I think a couple can manage with one car when retired provided that most of what they both want to do is within walking/cycling distance or there is excellent public transport. The nearest train stations to me are right in the city centre (where I would be travelling to so no help at all), in the town I used to work in, so a 20 to 25 minute drive or the 90 minute bus journey, or out in the middle of nowhere inaccessible without a car.
The biggest thing for me would be that I couldn’t keep my dogs because I have to drive them to where they can get decent exercise....so yes...on reflection my car is vital to me because of my dogs.
