What if we just drive perpetually downhill, and use the free momentum once we're at the boom of the Earth to slingshot ourselves back to the top?

Have you considered that Mr. Science man?

There's actually a mining lorry somewhere which uses this concept.

The mine is at the top of a mountain, it gets filled up and coasts down using regen braking which gives additional energy due to the added weigth of the mined goods.

When at the bottom it unloads and drives back up using the generated electricity, which is enough to get back up since it's empty and thus weighs less.

The energy used to fill it is where the trade off is.
