This already exists as GetAround and I used it all the time when I was in San Francisco. Similar pricing to ZipCar, but I found that there was typically better options&#x2F;availability (YMMV). The other big plus was that I was able to get approved by GetAround within something like 24hrs, where ZipCar I had to wait to get my key delivered (~2 weeks) or pickup my key at their office (during business hours only).<p><a href="https:&#x2F;&#x2F;www.getaround.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.getaround.com&#x2F;</a>
