The rental contract.

Starting with the concept of rental, this work aims to analyse alternative and more sustainable forms of mobility such as bike sharing and car sharing, and to discuss their legal regulation. Car sharing and bike sharing are services aimed at reducing the number of circulating cars in order to protect the environment and human life. We should not underestimate the fact that nowadays more and more often in various commercial sectors, businesses prefer to rent rather than buy goods/instruments, thus conserving cash and avoiding the consequences of their deterioration. Furthermore, the need to adapt production to market demands justifies the need to innovate goods with increasing speed. Even for private individuals, rental (short or long-term) is a tool that is increasingly used and incentivized mainly by vehicle manufacturers. It is necessary to identify the applicable regulations in this field: whether those concerning leases, or those commonly adopted to regulate mixed contracts (theory of absorption, combination and analogical application).
