Who Knew, Batman uses Onstar?!

Here are two ads I found in some old magazines from 2000. I always thought that Batman was so cool when he was driving around in the Batmobile. That car could do just about anything, and made KITT look like a remote control kiddie car. But it turns out that Batman actually had a little secret up his sleeve, or under his suit... or whatever you want to call it.
Have a look at these two ads which reveal his little secret!
