Being able to save your Gran Turismo 5 game during an endurance race is a feature "under development" right now, creator Kazunori Yamauchi has revealed.
"I'm sorry," he wrote in a tweet translated on GTPlanet. "Game saves during endurances: they are currently under development."
As it stands, finishing an endurance race in Gran Turismo 5 requires you sit there for four, nine or 24 hours and see it through.
Gran Turismo 5 is a success - particularly in Europe, where more than half of the game's total 6.37 million copies (as of December 2010) have been shipped.
The best selling Gran Turismo game remains Gran Turismo 3, however, with an enormous 14.89 million sales.
