Now here's a clever solution to prevent scraping the low front air dam on the Chevrolet Volt.
As you'll see in the video, a downward-looking camera is mounted on the front of this Volt. This camera sends imagery to the Volt's interior display screen, thus allowing the driver to see things that might impact the Volt's air dam.
"Always hated to drag the air dam on these things. Now, I can see through the dashboard!"
It does indeed appear as though you're looking through the dashboard, which is kinda cool, but more importantly the driver can now easily detect objects up front before the Volt runs them over.
