Carshare is particularly useful for people who either live in car-dependent areas and cannot afford a private vehicle, or for urban car-less people who enjoy a diverse array of transportation options that they supplement with driving for trips that require longer-distances, multiple stops, or more storage capacity [1], [2]. Carshare benefits from economies of scale in densely populated cities, and firms can more easily adjust their prices and grow their network flexibly according to consumer demand. Carshare is particularly effective when parking is scarce, there are transit hubs nearby, and land uses are mixed [3]. In lower-density areas, carshare can be more challenging to implement, as people are more likely to enjoy plentiful parking, own their own cars, and have fewer alternatives to driving that would make them more likely to choose to forgo private vehicles [4].
