Formula One cars go up to a speed of more than 350km/h, hence there are a number of risks associated with the sport. Every now and then, various measures are taken to make the sport a safer one, but accidents do happen.

The same was witnessed during the 2014 Japanese Grand Prix, where Frenchman Jules Bianchi crashed in the 43rd lap of the race as he crashed at a high speed with a crane tractor, resulting in head injuries.

Jules Bianchi fell unconscious and was soon rushed to the hospital.

Nine months later, the ugly side of the sport came into light as Formula One lost one of its young drivers, as he died on 17 July in a hospital in France following that fatal crash.

It is one of the darkest days in F1 history since Ayrton Senna, who also suffered an unfortunate accident during the 1994 San Marino Grand Prix in Italy, where he crashed against a concrete barrier and suffered head injuries.

Senna lost his life on the same day. And it was his death, which led to a number of significant changes to make the sport safer.

Former Indian Grand Prix driver Narain Karthikeyan, who has been inside a Formula One Car is aware of the dangers associated racing in those cars at a tremendous speed.

"I got this terrible news a little while ago and it shows again that it can never bullet-proof in a racing car, even though safety standards have improved by leaps and bounds in the last two decades. Unfortunately, it didn't look good from day one in Jules' case," PTI quoted Karthikeyan as saying.

Jules Bianchi drove in many other racing competitions such as GP2 series, British Formula Three amongst others, but the Frenchman was only a part of the F1 for two years as his last race was in a Ferrari-powered Marussia car.

There were lots of promise shown by Jules Bianchi, when he was behind the wheels. Though, Karthikeyan said he did not have much chance to interact with Bianchi, the Indian felt he was a 'talented guy'.

"He was a talented guy. He showed speed and promise in F3, GP2 and Formula Renault 3.5. He had the right people behind him. He could have achieved a lot.

"In F1, we did not speak much. Whatever little we interacted was in the paddock or in the drivers' parade," he added.
