No. If the clutch is in, there is no need to put in neutral.
Disagree.
It is possible for the clutch pedal to fail to disengage a malfunctioning clutch, or for a clutch cable to part while the vehicle is being started. In either case, the vehicle will lurch when in gear and the starter is actuated.
I know it is possible, because I hit the back wall of a barn with a dump truck when it happened to me.
Except for emergency scenarios (roll starting, or trying to use the starter motor to move an otherwise disabled vehicle), the transmission should be in neutral when starting, and not shifted out of neutral until the hand brake is released.
Justify that, please.
I hit a barn with a dump truck because the clutch pedal failed to disengage the clutch, and I was in first gear when I tried to start. In neutral, the truck would not have lurched forward, and I would have discovered the problem when I couldn't slip the transmission into reverse.
The transmission should be in neutral until the hand brake/parking brake is released, and you are ready for the vehicle to move.
