In 2009, Zipcar took 250 participants from across 13 cities -- and they're all self-confessed car addicts and car-sharing rookies -- and got them to surrender their keys for a month.
2009. aastal võttis Zipcar 13 linnast 250 osalejat, kes tunnistasid, et on autosõltlased ja autojagamises alles algajad - ning said nad oma autovõtmed kuuks ajaks firmale andma.
