Is Reality an Illusion

I have a basic idea of quantum theory and the unpredictability of sub atomic particles. My question is if simply observing something changes what it is (eg. photons acting as waves or particles). Does that mean when we look at large objects like a car that by simply observing it, we made it that way ? If the car is made up of a collection of atoms and electrons, wouldn't looking at cause electrons to behave in a certain way determining the position of atoms around it and atoms around those atoms until the whole car shifted its position in space ? Basically Im saying is what works at the micro scale should then be apparent on the macro scale.

Maybe not so much as to be noticable with the human senses but with sophisticated technology we could measure these movements over the whole object, like the car in this case. Any ideas or comments are appreciated the longer and more detailed the answer the better. Thanks ! :)

See quantum mechanics is applicable to very small particles less than 0.000001 m or 10^-6 m.
the molecules which are made of atom do not obey quantum mechanics. And large objects greater then 0.000001 m are bound to mechanics (Newton`s law of motion etc.)
