If the devs made it so that there is an option where there is no low-rpm autoclutch, imagine what would happen if some n00b stalled right on the starting grid! That would be terrible.

Sorry maybe someone should suggest a bad idea before you object to it next time

if you turn of autoclutch, the low-rpm autoclutch should be off too. a n00b wouldn't drive with autoclutch set to off anyway

I don't think either LFS or the Papy sims will allow you to stall the car with autoclutch turned off.
