Your post makes zero sense.
What does the cost of maintenance and insurance have to do with anything?
What does the size of the vehicle have to do with traffic jams? India is full of small cars and has terrible traffic.
What does road rage have to do with large vehicles?
I'm not sure where you're from but here in the US we have this thing called freedom. That allows us to spend our money how we want on what we want. Your opinion of "large cars" is moot and you're not going to change anyone's mind. That should be especially obvious since you made almost exactly the same post 15 years ago.
