Nico Hulkenberg is 'sleeping OK' but says he feels 'under pressure to do something'
Perhaps the biggest motivation for many drivers to keep pushing until the final lap of the final race is that their very futures in the sport are at stake.
Nico Hulkenberg recently delivered potential suitors Lotus an ultimatum that he wanted his F1 future sorted by the end of the month.
However, with the move dependent on Lotus securing a financial deal with Quantum Motorsports added to concerns about next year’s weight regulations, Hulkenberg told Autosport he is now under pressure.
There are opportunities out there and I'm sleeping OK. I wouldn't like to wait until the end of the season, that's for sure. I said in Korea that before the end of the month I would like to do what I'm doing. It's coming close so I have to hurry up. I'm under pressure now to do something. These things take time sometimes and you are negotiating and it's how things go.
Other drivers fighting for their F1 future include Ferrari’s outgoing Felipe Massa and McLaren’s Sergio Perez, with Force India, Sauber, Williams, Caterham and Marussia also yet to confirm their full 2014 driver line-ups.
There’s still a lot to play for!
