PHILADELPHIA (CBS) -- General Motors is scrambling to find a workaround for its high-tech solution to "valet abuse" that, unfortunately, just might be against the law in many places.

Even though it was a Ferrari, not a Corvette, that got run into a ravine in Ferris Buehler's Day Off -- and not by the rogue parking valet that ran up extra miles with a joyride around Chicago -- the movie crystallizes some drivers' fear of leaving the keys to their "baby" with anyone.

So, Chevy had a bright idea.

"The new valet mode with performance data recorder allows the owner to record video, audio, and even vehicle data," says an announcer in a promotional video.

But hold your horses, car fans!  Recording audio without everyone's permission (in this case the valet's) could be a felony in Pennsylvania, which requires all-party consent for recording audio.

It's also illegal in Michigan, where GM is headquartered.

The fix might be to obtain the valet's consent -- or to disable the audio recording feature.
