Sometimes, waiting for a government to step up just takes too long.
One encouraging development in the aftermath of the Delhi public transport gang rape/murder is the growing popularity of Cabs for Women by Women. Though a bit more expensive than hailing traditional male-driven cabs, this seven cab business is targeted towards middle class women who may need the flexibility that a public bus can't offer (and, in some cases, the additional comfort that only a trained German Shepherd can yield).
Back in 2009, India tried to balance the inherent sexist environments in their public transportation by introducing eight women-only trains called "Ladies' Specials." This concept is not new, and perhaps most recognizable to those familiar with the context of Japan's own uneasy subway culture.
Countries in several regions offer similar services for women today: Egypt, Iran, Taiwan, Brazil, Mexico, Indonesia, the Philippines, Malaysia, and Dubai. A good look for private-public enterprise responding to social lewdness--not so much a good look for those in power who have clearly failed to implement policies that provide safe environments to half of their citizens. Makes me wonder if these kinds of services will proliferate before the problems that prompted them in the first place begin to improve at all.
