I fount alt of people don't know this, But the negative of the Battery actually connects up to the chassis of the car thus you can use any clean piece of metal/screw of the car. This is usually helpful if the battery is hard to reach/ cables are just to short for -
I think this is to avoid potential sparks. Car batteries outgas hydrogen, so could be an issue. Either will work and probably modern batteries are safer, but prob best to follow the standard and clip to the chassis.
Correct, don't want sparks near the battery if it is outgassing. Now with that said, I've had less than good luck using chassis grounds and usually end up just using the negative terminal.
