those they have use to power satellites for decades?

Hm.. There's only one US nuclear reactor currently in orbit. SNAP-10A.

The russians had a reactor that deorbited unexpectedly and contaminated
parts of northern Canada in 1977.

The last two Mars rovers have had Pu-powered RTG's - radioisotope thermal
generators, which don't use fission, but rather are powered by the
heat generated as the Pu decays into daughter products. On the downside,
the power is limited to sub 1kw, which won't run a car for very long.

Satellites use solar panels.

DARPA is working with Lockmart on the Draco project to test a
new reactor design in space for military satellites - it will use
HALEU (High-Assay, Low-Enriched Uranium) rather than the HEU
(Highly-enriched Uranium) in the Draco test reactor.

"The demo system won't operate in an orbit where it has
any - even a remote - chance of coming back to Earth."

Might as well wish for a car powered by a Mr. Fusion device.
