You really don't ever need a car, with good public transit. You can use the delivery van or rent something twice a year, I'm sure.
Depending on geography, even delivery vans may be unnecessary; cargo bikes work pretty well on flat terrain.
I haven't ever had a car. Not in a hypothetical world where we built public transit, but here, in the present/past real world. Most of the times this has been a problem were caused by other people using cars, and I don't consider becoming part of the problem to be a solution there. It can be done.
