Impala - Chevrolet :: 2008 - Ignition Switch Failure?

I am the (once) proud owner of a 2008 Chevrolet Impala. I have owned the car for one year, putting only 12,000 miles on it (was 109,000 when I bought it.) The car has run quite well—I have not had any problems out of it (unlike the 1999-2005 generation Impalas). But, as many of you may have heard, GM had some massive recalls as of late. Many of the cars have had fatal ignition switch failures. Basically every single Impala in the last (my) generation has been recalled.

Take any other keys/paraphernalia off of the chain—basically, just insert the key into the ignition, unattached to anything. This is the fix for the time being, apparently—until they can get ignition switches for however many hundred thousand Impalas they have to fix.

I am about to make a 3 hour drive. Now, that wouldn't be the longest drive that I have made in this car (and I cringe at the idea that, driving 17 hours with a bunch of crap hanging off of my chain, that my car easily could have been one of the unfortunate ones.)

Now that I know that I cannot be sure of the safety of my vehicle, I need to know what to do in the case of an emergency. I want to know what exactly the situation of an ignition switch failure entails...basically, what happens to my car and my ability to control the car. Lastly, I need to know what to do if this happens.
