Every day, the newly opened Gurgaon-Dausa (Rajasthan) section of the Delhi-Mumbai Expressway sees Mercs, BMWs, Ferraris and Porsches, among others, scorching the concrete and stretching the speed guns meant for a much tamer job – of monitoring traffic speed. Racing up and down the expanse of the road, Grand Prix style, these cars easily breach the 200kmph mark. The top speed captured on cameras is 260kmph.
