Agreed. Carrying in cars should have nothing to do with a firearm on a public road. But that was NJ argument and NJ included that as a “sensitive place.” NJ legislators seen it as if you are in a vehicle on a NJ highway and road are considered government property. That restricted you to carry in the car on government own property in this case highways and roads. Even with a PTC, NJ expected you to follow Federal regulation while traveling which is gun in a case separated from the ammunition. Judge Bumb overturned that portion as there wasn’t no historical law for that and the plaintiffs proven that wasn’t reasonable based on NJ carjacking stats.

State roads are owned by the state. County roads are owned by the county.
Regarding roads and private property rights - there are 2 different types of people: invitees and licensee. A licensee is someone who has explicit permission. An invitee has implied permission. For example a Burger King - nobody has to tell you that you have permission to enter. It's implied permission and considered the default rule. The state attempted to change the default rule that says if there is not explicit permission that you're not allowed. Judge Bumb saw through that and struck it down as it would be a flat out ban on carry. This applies to roads as well.
