When it's in the car and you're not, it falls under standard storage laws like it does it your home. Therefore, it must be locked up.
I agree that standard storage laws apply in that situation. MGL chapter 140 section 131L states that the firearm must be stored in a locked container with a tamper resistant lock.
However, a locked vehicle meets those requirements, though a court/jury may disagree.
This is of course a gray area, and I would never leave a firearm in a vehicle unless it's in a locked box, but technically as I read it the law does not prohibit it as long as the vehicle is locked.
