[Bay Area developer Rick Holliday] explained it to laypeople like this: If a car company built cars the way a real estate developer built housing, the way it would work is that the developer would hire a contractor to come over on a Monday with four tires. The next day, a subcontractor would bring four rims and wrap the tires around them, then wait for a subcontractor whose job was to put the wheels on the car. The next day the transmission would show up and a new crew would weld it together. Finally, after two years of piecemeal assembly, there would a $600,000 car in the driveway.
