Mostly it is the "maldar bap ka beta"s indulging in this crazy pastime. Basically, lazy and spoilt guys, with easy money to throw around. Normally, they have a couple or more girls clinging to them, and what better way to impress them? The guys and girls are usually headstrong, high class loafers. Need to be "Macho", because they have seen the heroes in films and TV serials such Macho guys driving around crazy, with booze in one hand and a blonde on the other! In great, spanking new cars! Speed is the thrill. If it runs over and kills a few poor sleeping on the platforms, well, no sweat, they can get around, the dads and chachas and the moolas are there! Haven't the top heroes also done it?
Tell you what, if recklessness is obvious, put such offenders straight behind bars. Make it minimum 5 years inside. Impound vehicle. Cancel licence. Impose hefty fines: Rs. 20 lakhs for loss of a life, Rs. 15 lakhs for causing injury. And give Police the absolute authority -no interference from top figures!
