It the same for manual.
As long as gear 1 is engage for manual car, it will still move forward when u release the clutch (without stepping on accelerator) . Like auto car, only way for manual car to stay still is to engage neutral.
1 good thing about manual is you can change reverse gear without having to look at it.
2 good thing about auto are: when you are on a gentle slope, your car will neevr back roll.when you are in a peak hour jam,auto save a lot of hassle
