Narain Karthikeyan, who made his Formula One debut in Melbourne last week, says his true potential will surface only after the first seven races where he would be aiming for the chequered flag.Happy with his 15th place finish in the season opener, the 28-year-old Karthikeyan says he has made many people sit up and watch him perform. "It (debut in Melbourne) was a case of driving alongside high profile names. I want to establish myself as a good driver. After the first race in Melbourne, a lot of people in the business are recognising that," Karthikeyan said over phone from Kuala Lumpur where the Indian would compete in his second F1 race on March 20.
