The network analysis also highlights that while fuel efficiency and battery capacity are key factors, other vehicle features, such as advanced safety systems (F17) and in-car technologies (F10), play a crucial intermediary role in the decision process. The high betweenness centrality of these nodes (0.1001 and 0.1243, respectively) suggests that they connect otherwise disparate considerations, making them essential for enhancing the perceived value of vehicles. This underscores the importance of platforms integrating and promoting these features to appeal to a broader user base. Moreover, the short path length demonstrates that small improvements in features like safety or comfort can have a substantial and rapid impact on users' decisions, highlighting the sensitivity of the decision-making network to enhancements. Given the low density and the interconnectedness of key vehicle features, platform operators should prioritize optimizing connections between underrepresented factors in the network. For example, while fuel efficiency and battery capacity are well-established as primary decision drivers, additional vehicle features such as advanced safety systems and in-car technology could be further integrated into the network. By doing so, platforms can enhance the overall value proposition for users, making the car selection process more holistic. Moreover, the short path length indicates that improving even one feature, like safety or comfort, could quickly affect the user's overall decision, showing the sensitivity of the network to enhancements. According to the analysis, 47% of respondents are homeowners, and 41% of renters emphasize the importance of flexibility and accessibility as key factors in choosing car sharing. These results correlate with a study by [PERSON] and [PERSON] [68], who indicated that people living in urban areas are more likely to utilize car sharing due to the limitations associated with owning and maintaining a personal vehicle in cities. Furthermore, our data indicate that, as 38% of the respondent population, two-person households represent a significant group of potential car-sharing users. This finding aligns with the observations of [PERSON] and [PERSON] [69], who noted that smaller households are more likely to consider alternatives to owning a second car. Another crucial management implication for peer-to-peer car-sharing platforms is adopting an open innovation strategy tailored to engage both vehicle owners and renters. In the context of P2P car sharing, open innovation can involve co-creation initiatives where users--both vehicle owners and renters--provide feedback on platform features, pricing models, and types of vehicles in demand. This strategy is supported by [PERSON] [70; 71; 72], who emphasizes that leveraging external ideas fosters innovation in user-centered services. Case studies from peer-to-peer platforms, such as Turo, show that incorporating user feedback into platform design, like insurance options or service fees, can increase trust and engagement among both parties. Building a community of active participants is vital for the success of peer-to-peer car-sharing systems, as the user experience directly affects platform growth and sustainability. Additionally, the result that 45% of families with children are interested in car sharing is significant. Research by [PERSON] et al. [73] highlights that safety and adaptation to the needs of families with children can significantly influence the decision to utilize such services. Regarding the frequency of vehicle use, our study shows that individuals who use vehicles less than once a week may be ideal candidates for car sharing. [PERSON] et al. [74] observed that car sharing can complement traditional forms of mobility, particularly for occasional transport needs.
