Mr. Pierpaolo Cazzola:

If I understand the question correctly, it is whether there are good motives to shift rapidly to shared systems. There is a need for systems that offer a better value proposition for cars. There are solutions that require, for example, policies such as road space reallocation and making modes of travel available that can complement or feed public transport services. For example, the potential of mobility as a service could be tapped into and different ways to move integrated. This also needs to come with sticks and parking policies can be a stick to get people to move away from cars towards public transport. Parking policy can also be differentiated by greenhouse gas emission performance of vehicles so it can help with the transition. Simply making part of the city harder to access by car and ensuring that there is a better offer with public transport means that people would switch towards that. This helps shifting uses and choices towards modes that are inherently more energy efficient. That helps to move to the low energy demand scenario by altering people's model choice. I am not sure I got the idea of sharing buildings or housing. Denser neighbourhoods are more prone to being favourable to choices other than car travel. There are other choices related to urban planning, transit-oriented development, or the integration of different modes, which can ensure that even in a scenario without technological breakthroughs, there is a move towards a scenario that is compatible with lower energy demand.
