When parked, manually open the spoiler.
Shove a wad of paper in there and clamp down on it with the spoiler.
Take car for a blisteringly fast ride.
Then when pulled over for speeding and littering check to see if paper wad is missing.
If no cops around, just pull over and check to see of paper is missing.

Assuming everything is on automatic (ie I did not press the spoiler extension button and the LED light is off) If i start to go over 120km/h for an extended period, how do I know if my spoiler came up while im in the car? does the led light actually light up by itself? I mean if im in the car and the light is off - but im doing well above 120km/h- is there anyway to know if the spoiler is up while im driving? thanks!

If you put a temp sensor on your refrigerator light bulb you can monitor it easily, with the door closed. Let technology solve technology problems.
, the technology may be so advanced that the light only goes on and off when a person is actually checking to see if it's working properly.

I always thought about that conundrum. Then I realised that the question 'Does it make a sound?' is deliberately phrased to be ambiguous.
I'm not a physicist but it seems to me that the following happens: when a falling tree hits the ground, the sudden impact with the ground creates sound waves (which exist whether anyone is present or not). Those sound waves travel through the air while disturbing air molecules. If a person or animal is present, their ears will sense that disturbance in the air molecules.
By 'making a sound', do we refer to the existence of sound waves or the ability of a person or animal to sense those sound waves as 'constituting a sound'?
Just my 2 cents...

But how can I be 100% positive the light in my refrigerator goes out when I close the door?

Sorry for this silly post but I was a Philosophy major (please pity me) and I've always found the "tree falling in the woods making a noise if no-one is there to hear it" a very ego-centric conundrum and yet no conundrum at all. It's like asking if an eclipse hides a planet if no-one is looking, i.e. did the eclipse really happen? Of course it did, just as the falling tree made a noise totally independent of ears to hear it.
