A 4dr crew cab can haul the kids to soccer and move furniture all while requiring one parking spot. It's a good multi-tool at the expense of operating costs. The cost of insurance, registration and (possibly) parking buys a hell of a lot of gas.
Think of a vehicle as having indoor storage, long term comfort (space to not be cramped) outdoor storage and passenger capacity. Crew cab trucks are used like full size sedans with outdoor storage instead of a trunk. That's a pretty good blend for most use cases since most people can use the second row as a trunk when not carrying passengers.
Insurance, registration and parking costs are a disincentive to buy specialist vehicles (like the electric commuter cars HN loves).
