Talk to anyone in Bangalore two "truths" come out very soon. Auto drivers drive really bad. Taxi drivers drive really bad. Talk to someone who drives Santro and the next truth would be Swift drivers are next after Auto and Taxi drivers.
If you say all drivers are bad it is not useful information because it applies to everyone and their is nothing you can do about it. If you say driver of car KA 08 XXXX is bad, it is probably correct but not useful again (How many car numbers can you remember?). So I feel that humans (at least in Bangalore) generalize it to a point where the information can become big enough to look useful. Avoid meddling with Auto, Taxi and Swift drivers. Cool...I imparted some wisdom ;) It doesn't means it is correct..it only means it is now worth discussing/talking about.
