Consider the idea that we could do with a different regime altogether for vehicle registration or a fiscal framework that takes into account congestion and pollution together. Consider the idea that the Centre and its various arms such as petroleum and industry ministries work in harmony with the Delhi government and with each other. Consider a Union budget that makes sense to all in fiscal incentives and disincentives. Consider a glorious scenario where courts and prime-time TV news anchors do not have to ask questions that lead to actions but one where coordinated action elicits a timely effect.
Maybe this is too much to ask, but there is clearly a case of various arms of the government taking ad-hoc measures in silos, when what we need is a long-term roadmap in which industries and civil society, in general, can look forward to a timeline that offers long-term solutions rather than throw up knee-jerk responses.
