I love Delhi's JBM ecolite buses, cool handy features in them especially for senior citizens, and specially abled persons. This is category of people which needs most care while traveling in Pune. Plus buses are Made in India.
LOL fossil fuels are on the way out. More and more solar, wind, tidal, geothermal and quite possibly Nuclear Fusion(FAR more efficient than that of fission) will become more available and cheaper in the future. With the exception of fusion obviously.
