The Rajya Sabha on Wednesday saw light hearted banter when Transport Minister Nitin Gadkari, while making references to the norms for new cars, said once a hero or heroine has played a character role it is very difficult for them to go back to becoming lead actors again. "It is very difficult. Once a heroine has been cast as a character actor, it is very difficult to recast a character actor back as heroine," he said, leaving members in splits. It's the same for a hero. Once a hero is cast in a character role, then one does not get back the hero's role," he added. Gadkari was responding to a question by BJP's Roopa Ganguly, who asked if safety measures available in new cars can also be fitted in old cars. However, apparently mindful of the sensibilities of Ganguly, who shot to fame with her role as Draupadi in the epic serial Mahabharat,Gadkari later clarified, "Actually, my comment was not against anybody. Take it lightly." He said it is difficult to have rules for old cars and the new norms and regulations only for new vehicles. For old vehicles, it is very difficult mechanically to make them competent, Gadkari added. He, nevertheless, noted some of the latest safety features can be made available in 2-3 years old vehicles, too.
