Should I trust the iPad?

I'm sure you've seen these before. The iPad is a thin slip of...something...that rests on your car's dashboard where it clings tenatiously to your iPod as you drive around. Using no adhesive, magnets or other sort of trickery, it's the iPad's surface that keeps your iPod in place. It really sounds great, as the dashboard is a handy spot, and not having to slide the 'Pod in and out of a case to change songs on the highway is another plus. But is it trustworthy? I can easily picture my iPod being hurled into the windshield, or flying out of the passanger side window as I make a sharp turn (you really need to drive with me sometime). If you've used one of these, what has your experience been? I'd love to get one, I just need some reassurance from experienced users.
