Observed something interesting today !!

So I am from Bangalore, was waiting for a Friend today near a busy signal, and i happened to observe the traffic for good 5-10 mins in that time span I observed a minimum of 50-60 Cars (excluding can) having a single driver, and I am not talking about cars like Comet they were big cars 5-7 seater, Pajero sport , 700's, Creta, hector, taigun, Scorpio etc... and mind you this traffic was just from one lane, moving towards tech parks and hospitals, banks and other offices.

And I suppose this issue might not be limited to Bangalore but most of the metropolitan cities.

So what is causing these single commuters to not travel in public transport, or atleast take company transport like cab or bus? Is it only because of the comfort or because of the societal status/image.

If anyone of you are single commuters using big vehicle please let me know what is causing you to do so?
