Left lane begging

As usual.. something stupid... read on if you are a stupid!! :P

There has been a radical shift the way beggers choose their target audience. Until a month back, it was the right lane people (Ones sitting in cars, autos) that they used to focus on! Very recently, they have shifted to left-lane audience (Drivers of heavy motor vehicles alias lorries). I was so confused and the waiting is so long i started to think of potential reasons for the strategy shift!!

a) The car/auto fellas are feeding this community for too long and out of their "beggar budget"
b) The lorry driver's one rupee has a more emotional-rupee effect than a car owner's one-rupee
c) All beggars suddenly tried to enter the previously ignored niche market of lorry drivers creating a "nishe-urpulus"
