it is nt true that you can carry. you are allowed to carry a loaded weapon in your car, WITHOUT permit, as long as it is either; in closed compartment(ie center console, must have lid) or glovebox, or you can have it in plain sight, like on the seat or anywhere. side door panels are excluded and considered concealed, under seat is concealed.....anywhere that it out of sight and doesn't have a closing compartment is illegally concealed.
you can carry the gun concealed from your home to car or vise versa and your car to office and vice versa if your office is on private property
you are not allowed to carry your gun on your person concealed without a license, outside of those exclusions. the permit takes like ten minutes to get and is under 70$, I recommend getting one when you get a chance.
