Ridesharing also fills a significant void in late-night transportation options. In most major cities, transit is either non-existent or very limited between 10pm and 4am. Research done by the American Public Transportation Association shows that ridesourcing now accounts for a signficant share of late night/early morning alternative transportation. So perhaps ridesharing alleviates the burden on local governments of needing to provide more late-night transit options. But is that a good thing?
