You can answer all of those questions, and get a decent knowledge of how
a car works, without understanding the internal combustion engine. You
don't need to understand the Otto cycle to understand gears (heck,
anyone who has riden a bicycle understands gears). You also don't need
that to maintain your car (the Otto cycle has nothing to do with why you
should check your oil, or what a radiator does).

You don't need to understand about the molecular frequency of water to
answer those questions. You know you shouldn't put the cat in it because
it will cook it. As for metal, could you please explain to us why
putting metal in the microwave is dangerous?

How much do you know about semi-conductor electronics? Do you feel that
this knowledge is necessary to operate a phone and a computer or do you
feel it's enough to read the manual?

I agree with the sentiment of the last paragraph, but I think that your
examples were poor. You don't need to know the Otto cycle to maintain
your car and you don't need to know what a molecular dipole is to know
not to microwave your cat.
