Tell us about yourself!
I do not think that the clutch needs to be depressed, that is only required when starting car by the key in momentarily "start" position, in order to complete electrical circuit for starter motor. The reason is NOT to start engine by mistake if gear is engaged. By requiring to press the clutch then doesn't matter if gear is engaged or not.
I do not see any roof. If it is raining, it just rain there ?
