Carrying large packages, suitcases, or shopping bags on transit is awkward at best and impossible at worst. Anyone who expects to travel with such cargo, even if only some of the time, will do best with a car.
In 2007, Ikea opened its first store in Portland. It is 280,000 square feet, has around a thousand parking spaces, and is near a light-rail station. How many people who plan to do more than just window shop do you imagine carry their purchases home on the light rail?
Drag right to see the Cascades light-rail station, which is much further from Ikea than any of the parking spaces.
