And yet Countries who decry this still support that regime by buying Oil from them. Too bad the West does not have any backbone. Really it is time to stop Oil Subsidies and put all that money into alternative, including nuclear.

Edit: Here's another link that seems to show a general decline in Saudi oil imports by the US over the last decade.

The amount of hypocrisy in Western culture is really quite amazing if you look carefully. Criticizing other people's regimes is fun, criticizing your own is not so much fun it seems.
A car engine is less powerful than a spaceship, but radiation is your enemy. It's not just "Oh we need some shielding, slap some lead around it!" kind of enemy, it's "if your body absorbs ten joules per kilogram of body weight, then you die, it take a few days, and it hurts the whole time. Your modern car engine produces around fifteen thousand joules per second (and that's when it's cruising, multiply that by ten if you're accelerating as hard as you can). If you are in a crash and the shielding is breached, you die and so does everyone else nearby." - https://worldbuilding.stackexchange.com/questions/69576/prac...
The thickness of shielding needed to turn that radiation into safe heat is a bit challenging to calculate, but can be approximated with the mean free path, which for gamma rays at this per-photon energy level is in the order of 1cm. You need to reduce it by 1000 to not die immediately, a million to survive going to the shops once, a billion to regularly commute, and probably quite a lot more before regulators are happy. As it's an exponential, those correspond to (10, 20, 30) centimetres, all multiplied by some fudge factor because I'm handwaving a lot by saying the mean free path is 1 cm without giving a lot more specifics.
30 centimetre thick shell surrounding a 1 meter cube has a volume of about 3 cubic meters, massing much more than your car regardless of what you make it from. If you made it from lead, it would mass 34 tons.
Unfortunately, the radiation shielding also has to cope with neutron radiation, and the best materials for neutrons are the light elements while the best for gamma is the heavy elements; and even more annoyingly, absorbing neutron radiation causes the emission of gamma radiation.
This is also why we won't get a Mr. Fusion powered electric DeLorean even if someone figures out One Weird Trick That Makes Farnsworth Fusors Useful: fusion reactors are even worse than fusion for the instantaneous radiation output per unit energy, the advantage in this regard is (IIRC) that the radioactive waste from fusion is easier to deal with than the waste from fission.
