That's not really a fair comparison; the same car costs more in India (I believe) than in the US, if you are comparing say a 2011 BMW 335i Coupe. India does have much lower end cars available, so "a" car can be cheaper, but Indians pay a premium to buy imported cars. It's nowhere near as bad as in Singapore or Malaysia where cars are marked up 200-300% though.
There's some argument that a secured loan like a mortgage or car loan should be cheaper than an unsecured personal loan. Education loans in the US are often federally subsidized, but if they were treated as regular unsecured loans, they would be higher than car loans, and much higher than mortgages. There's a good argument for government subsidy to education, but it would have to be a subsidy to make it cheaper.
