I sold my car after I realized that I'd made it through a particularly brutal Wisconsin winter using only my bicycle to get to work and back. In the meantime, I used the car about twice a month to get groceries. The car was 20 years old, and I really did not need it: it seemed like it would be a good time to rehome it while it still had some life left.
My significant other did not have a license, so that was no big deal. Everywhere he needed to go in our small town was within two miles.
I used the money from selling the car to buy another bike and a cargo trailer. Grocery collection - sorted.
