That's what that little button on the trigger guard (on the 870 I mentioned) called a safety is for, but as a consession, if you don't know your firearm or anything about firearm safety, I agree, I wouldn't want you to be walking around with a loaded gun either.

P.S. By the way, I've only been in a cab once, it stunk so bad, that since then, I've always made other arrangements.
