Well, as you all have pointed out if the vehicle is stolen they have all the time in the world to disassemble any mechanism and obtain access to the firearm. Just like if they break into your house and they have 12 hours of you not being home, they are going to get into almost anything you store your guns in if they want in. It comes down to what risk are you comfortable with, leaving your firearm in less secure place for part of your day, not having your firearm the entire day, or risk losing your right to possess a firearm if convicted while carrying somewhere off-limits.
Those safes you mentioned that go in the console - they did not look that secure to me. It looked like they would be easier to get a pry bar in to pry it open. The Titan safe would at least be bolted under the seat and would make getting leverage on it more difficult. The RAC looked the most interesting, but they could at least get your magazine it seems. I was considering something that I could even move between vehicles (e.g. wife's car, rental, etc.) and the Titan looked like it would fit that bill.
Nonetheless, if someone steals my vehicle, the gun is really one of the last things I am concerned with. If they have enough time to try to defeat a safe where it is parked, it may have been a better to leave it at home. One thing I would definitely encourage you though is not having a bunch of junk in the vehicle that makes someone want to break into it and potentially find the firearm in it. Having a radar detector, GPS, fancy car stereo, etc. is going to be an attractant, and the gun is just going to sugar coat the deal once they are in.
