So, apparently, basically anyone can roll through the state with a gun in their car. Check out section 40 subsection e. This is less strict than Michigan, right? I also couldn't find any extra restrictions for driving through the city od Chicago.
I just thought it was interesting because I've always heard that Illinois and Chicago in particular have draconian gun laws but it appears more lax in this specific scenario.

(2) is eligible to carry a firearm in public under
the laws of his or her state or territory of residence, as evidenced by the possession of a concealed carry license or permit issued by his or her state of residence, if applicable; and
(3) is not in possession of a license under this Act.
If the non-resident leaves his or her vehicle unattended, he or she shall store the firearm within a locked vehicle or locked container within the vehicle in accordance with subsection (b) of Section 65 of this Act.
