What would it take to make bikes as standard a component on cars and trucks as spare tires? When a car breaks down, the driver is stranded. When parking is scarce, walking from an available parking spot to one's destination can be time-consuming. If bikes were built into car/truck chassises the way spare tires and jacks are, they would not compete with trunk room or obstruct rear doors/trunks the way bike racks can.
Has this idea been discussed before? Has it been tried? How would you design a bike to fit within the frame of a car or truck so it's out of the way but can still easily be removed and stowed?
Would people develop different parking behaviors and take advantage of the built-in bike, or would they largely ignore it, the way people ignore the spare tire and call roadside assistance when they get a flat?
