Doe anyone else in your household have one? Do you have a bus service, do your kids do activities miles away from where you live.
I acknowledge it's not feasible for everyone, particularly if people enjoy living in remote communities, or simply like their cars.
We're big fans of Dutch and Danish town planning, and of their bike cultures (from tots to great grandparents). What we've witnessed is that an environment can be created for citizens, in which the car is simply not necessary. Chris Boardman has made a great short film about Utrecht:

We don't run a car at all, and that means where we choose to live, work, activities & amenties are all considered within bike distances. It didn't feel difficult, or at all, a limitation. We also thought about local public transport options (there are bus & train services) before we moved here.
In very rare occasions, it's easy to call a taxi or hire a car if needed....
Aside from the devastation of coronavirus and it's future impact on cycling, it will be interesting to see how much Andy Burnham and Chris Boardman will be able to effect real change in Manchester, and then, if that will influence further positive opportunities for citizens throughout the UK. In the Netherlands and Denmark, the bike infrastructure was comprehensive to the point that it extended through to village level - not just cities and towns. I don't think that's impossible for us too.
One thing for certain, once you've cycled in Denmark and the Netherlands, you'll never feel the same about what we have (or put up with) here.
