| Trip activity | Charoniti et al. (2020), Jian et al. (2017), Wu et al. (2020a) | A smaller car may suffice when commuting or traveling to a meeting; heavy-duty purposes (e.g. moving goods) may require a larger car |
| Frequency of use | Paundra et al. (2017), Münzel et al. (2019) | Carsharing customers are not necessarily frequent users; many use the service only occasionally |
| Multimodal mobility | Ampudia-Renuncio et al. (2020), Becker et al. (2017a), Carrone et al. (2020), Clewlow (2016), Mishra et al. (2015), Münzel et al. (2019) | Frequent travelers tend to combine use of carsharing with other modes of mobility such as walking and biking |
| Influence on car ownership | Firnkorn and Müller (2015), Jochem et al. (2020), Ko et al. (2019), Le Vine and Polak (2019), Loose et al. (2006) | Some studies report evidence of a reduction in car ownership as a result of engagement in carsharing |
| Trust | Hartl et al. (2018), Julsrud and Farstad (2020), Ma et al. (2020), Wilhelms et al. (2017a) | Trust is especially relevant for P2P carsharing because of the higher economic risks and the absence of regulation |
