Or like Kentucky, as long as it's in the GLOVE BOX it's 100% legal to carry, locked and loaded. Of course if you have a Concealed Carry license, you can do pretty much whatever you want. ;-)
3-steps laws are stupid... Why would you even think about that bullcrap? BTW, the ONLY way to get the laws changed is to contact the people who make them and tell them about your frustration with the current law. It does work occasionally. Tennessee is a pretty conservative state, it probably wouldn't be too hard to get laws like those changed.
That's my two pennies...
