Dear Friends, why use car or bike for commuting inside city. One can use bicycle instead, it will save petrol or disel, reduce pullutants,no traffick cojection on road, less accidents on road therefore higher road safety, increase in the fitness, no need to go to Gym or take medicine for weight reduction so great savings! Billions of barrel of petrol will be saved if everybody start using bicycles inside city therefore great savings of foreign exchange and reduce the national expendature on petrol or disel, boost to economy. For senior citizens, disables car option may be ok. Lot of problems in the life may get sorted out. Please think seriously. It may look embrassing if vice president of a company start coming on bicycle but slowly one will be used to it, it is all mind and ego.
