You require absolutely extreme conditions for it to happen.

No you do not.

On earth, you will only find it happening in nuclear reactions.

Not true. Just you repeating it ad nauseam does not make it so.

You have been given examples of how it happens outside of nuclear
reactions, and even a link to a government sponsored science site
where it states categorically that a car with increasing velocity,
and thus increasing kinetic energy, increases in mass.

If I sit on the moon, the car will have increased mass on one side of
the orbit to the other, that doesn't mean it actually changes its
mass as anyone standing next to it will be able to confirm.



That's because they are stationary with respect to the car. If they
were measuring from somewhere else, it would.

You dont understand vectors either..

I do, you don't appear to though.
The car doesn't have different energy just because I move

It does.

Try hitting a car when you are moving at its exact velocity less a
teensy bit, and when you are standing in the road ..


but it does
have different mass according to your use of Einstein's e=mc2.
