If, when preparing to drive your car, you inadvertently pull the lever on the left instead of the one on the center console, do not drive away. Get out of your car, open and shut your hood, then get back in a proceed to drive.
Yes. This is from experience. You could head down the highway, and have your hood fly up, smashing into your windshield. It really is rather disturbing. It is also rather expensive to have your hood replaced, and your fenders repaired where the metal arms of the hood twisted grotesquely under the strain. Probably what your knees would look like, were they forced to bend in the direction they are not supposed to bend. Or elbows, I suppose. Either way, it was not pretty, and it was just plain stupid.
That was in January. I can talk about it now.
