How do you Re-Boot going 100km/h ?

The new Chevy Volt, developed by GM with a ton of help from IBM, brags about having more lines of code that the 787 Dreamliner  (that's an airplane, by the way)... My question, as you guessed, is what happens when there's a bug or it needs a software update?  Do I have to pull over and wait for a download?  Do I have to accept the new End-User License Agreement?  What if I don't?  Will my car stop working? I'm very curious to see how GM, not typically known for it's open and forward-looking view on technology, deals with some of the new challenges it may face.  Now, that being said, I volunteer to test drive one of these bad-boys and give my opinion.
