Unbelievable variance here. In my state car IS an extension. We also offer CCW permits. In my fled home state, the fucking weapon needs to be locked in box "A" & the ammo needs to be locked in box "B" or you are in violation. No permit is offered either at this time. A third case exists where a motorist in gun-friendly state A drives into state B. Some states will allow the motorist to retain the weapon in the passenger compartment. loaded and accessible, provided the motorist is passing through the state (not stopping for visit). Other states, usually those unkind to their own citizens require that the weapon be stowed in the trunk (often unloaded with ammo locked seperately) BEFORE crossing the state line, whether you are passing through or not. packing.org has a state by state list of all this. Moreover, I have never heard that rifle crap. In other words, it comes as no shock to me that some cities or states enforce/overenforce the law on all guns or ones in particular, but there is no nation wide policy governing what you can/cannot have in loaded & accessible in your car.
