According to the PoR and Einstein, all inertial frames are

So if I am driving my car at 100km/hr along a road, the Earth is
moving at 100km/hr in my frame. I calculate that its KE is, say,
10^30 joules.

When I stop my car, the earth no longer appears to be moving.....and
its KE is now zero.

Where has all that energy gone?

....or was Einstein completely wrong?

Oh dear, here we go. Looks like it's time to teach Hank some basics of
freshman physics.

But this is very good - if he manages to understand Newtonian mechanics, he
may be ready to explore SRT. :-)
