The utility I get out of the car, in absolute terms, is incomparable to my ~$1500 bicycle(that I purchased for utility and even commuted on for several years). I have slept in my car many times. My car has snacks, spare clothes and shoes, a blanket, a pillow, towels, pen and paper, bags for groceries, kick scooters, folding chairs, spare chargers and cables, amongst other things.
Regular people need to bring things they own with them and take them back home. Bikes are trash for that. When I’m on my bike, my credit card serves the function of space.
