In Ohio, with a CCW in a vehicle it has to be in a HOLSTER, on your person, or in a zippered pouch, or in your glove box, or center console. Your glove box, or console doesn't have to be locked. But gun must be concealed.
I almost always carry in my front pocket of my pants. In the old days they used to call my body type......Husky.....which nowadays means Fat. Needless to say getting to my gun from my pocket presents a contortionists nightmare. Same thing when I occasionally carry at 4 o'clock IWB.
The center console has it's own problems.
In the winter I just transfer to my coat pocket, usually the inside pocket on the left, almost in the same area as a shoulder holster. but for summer....
I have slipped into a gray area. I took a right hand Uncle Mikes holster, sewed a flap on the front ( barrel ) part of the holster, that wraps around behind the holster and velcros to the front side. I have wrapped this around my seat belt.
I can transfer from pocket to holster, and slide the holster on the seat belt to cross draw, and down to my left enough to be concealed.
Now I don't know if this would still be considered " on My person" or not.
I don't like leaving my gun in the car either. But sometimes this is a must. When this occurs I use the metal cabled lock box.
