Yes, if I say so myself, it's fine. (
Don't say this about others!)
The other day, after reading this thread, I realized that I didn't fill the windshield washer fluid reservoir for the longest time. I tried it and it was empty... Thanks for the reminder.
But, after buying the jug at the local "Social Safeway" (good to -20ºF) and filling with the help of a funnel, I left the parking lot without realizing that I had forgotten to re-install the hood. From within the car, I can't see if the hood is in place or not... Coming down Wisconsin Ave. towards the heart of Georgetown, I noticed that a lot of people were looking at the car. No wonder. An attentive passer-by and his two teenager boys told me that "the hood is open"! I wonder how far I would have driven with the plastic pannel hanging by its two claws? Luckily, the speed wasn't high enough to result in it becoming loose...

So, it's not a windshield fluid idiot light that I need, but an "open hood"... like the "open gas tank flap"!
