What he meant to say is, no there is currently no way to remove the clutch you speak of. The reason? Stalling is simply not yet implemented. Though it has been requested quite often and I'm sure it's quite high on the developer's to-do list
Would be great if stalling was enabled to enhance the realism even more. Also, if you don't let the clutch out right the car should 'bog down', that way it is even more realistic to get a good launch.
