The law has changed. As has been stated, your car = your house. No government permission slip is needed to exercise your 2A rights in those two places at least.
Then the state figured out they could make money on it...
Actually I think it was an accident of history. The result of some poor legislative drafting by some people who did not understand the history of licensed carry, or trouble themselves to look at the current status of the law. I've studied it quite a bit, as I was around when the change was made, and I think there wasn't any "intent" at all - just ignorance.
