There is a setting to tie in head movement to steering input. Can't remember what it is off hand. Probable in control settings or view settings. Or might even be in the driver settings.
In real life will 1st gear, no throllte and no clutch make engine to stall. Because engine stalling is not modelled in LFS, clutch is automatically applied when stalling RPM treshold is reached... check the blue bar in the right-down corner of the screen. It shows clutch.
Engine braking is in, but your clutch is automatic so you do roll backwards. I'd like to see support for a button clutch so us two pedal players also have to prevent stall when we spin.
Having not used pedals yet. (I will when I get my next rig) I don't know about pedal stuff. Do you have full capability? I assume from your current chat that you can't slip the clutch or balance the car on the clutch. AM I right here or is LFS about to blow me away yet again . . .
it seems that turning off the auto clutch is possible if you have a third pedal and use it as an analog clutch, or you can bind a key if you use a joypad , and you have a digital clutch
