There are currently one billion cars in the world. It is estimated that this number will double in the next few years. Every car uses approximately 2.5 parking spaces: one at home, one at the workplace, and one at the shopping or sport centre. This has a significant impact on the need for parking space. At the same time it is highly likely that we will be using self-driving cars in a few decades. According to research conducted by the Massachusetts Institute of Technology (MIT), this could lead to a decrease in the total amount of cars in the cities by 65%.
