Research? Ok.
India has a population of 1.21 billion with 15 motor vehicles per 1000 people. Which means India currently has around 18,152,901 motor vehicles. Which is just over half the population of Canada. Canada's estimated population doesn't even approach half of India's population. India's passenger car industry also produced around 3.7 million units in 2010 and is on course to become the 6th largest passenger car producer in the world.
Canada has an estimated population of 34,650,000 with 620 motor vehicles per 1000 people. Which means Canada currently has around 21,483,000 motor vehicles. Which is quite a bit less than almost everybody. Canada's automotive production output is seemingly marginally less than India.
I short. I don't think you're quite grasping the sheer scale of India's population compared to Canada or the current pace of development there.
