Seeing unconcealed carry in a vehicle described as 'concealed carry' bothers me more than it probably should, especially coming from 'experts.' The penalties may be the same, and unlicensed concealed carry may be addressed in the same code section as unlicensed vehicular carry, but "concealed or otherwise" shows that legislation recognizes that not all vehicular carry is concealed.
I'd like to see vehicular carry opened up, but that will be no mean feat when so many people equate it with concealed carry.
That said, I do understand why some people tend to just lump the two together and call it all concealed.
As for there being no license to carry openly, there is no requirement to carry a license beyond 30 days after the purchase.
MCL 28.422:
(1) Except as otherwise provided in this section, a person shall not purchase, carry, possess, or transport a pistol in this state without first having obtained a license for the pistol as prescribed in this section.
...
The licensee may carry, use, possess, and transport the pistol for 30 days beginning on the date of purchase or acquisition only while he or she is in possession of his or her copy of the license. However, the person is not required to have the license in his or her possession while carrying, using, possessing, or transporting the pistol after this period.
The license is required, they can perform a query by serial number, and stopping just to check for a license is apparently acceptable. Why would they not have grounds to stop a person to run the pistol's serial, and confirm that a license was obtained, or to stop and confirm an exemption from licensure?
