No open carry as you know it in Georgia so plan on concealed carry for all practical purposes.
Yes, you can "wear" your concealed gun while driving assuming you have a Georgia CCW permit/license.
That part about having the gun in the glove compartment is for people who do NOT have any CCW permit.
I just came back through Georgia last week and it was a pleasure to open carry in your state, as always.
Hopefully we'll get that here soon.
