What is the realestate of an unused parking lot worth? What if shopping baskets grew pedals and you just rode them home, leaving the parking lots mostly devoid of cars? Why are supermarkets not leaders in the elimination of two-mile car trips by championing cargo bicycle shopping? They could provide single speed upright posture trikes that carry full baskets of groceries. Sell advertising on the baskets and let shoppers just ride them home and back. They don’t need to be fancy bikes, they just need to be accessibly built and not tip over.
