I agree with you, except for the super-critical issue. There is no evidence to suggest that the weight of matter would be regulated properly. There are no uranium petrol stations present, so they must be produced with enough to last a 'lifetime'.
There are fuel stations present in the wastes. While replacing spent nuclear material is likely a bit more difficult than just dumping flamable liquid into a storage tank in a vehicle, one can assume that if the technology had reached a state where it was a common consumer product the infrastructe existed to support the technology.
Besides, if we want to take inductive reasoning to its conclusion, you won't find a compelling argument for a nuclear bomb in a car. First, we know that the vehicle is not carrying weapons grade fissile material. Second, we can assume that as a common consumer product, the fuel in the vehicle would have to be insufficient to achieve a super critical state. Third, we know that there is insufficient mass of material required to allow the fuel to naturall become super-critica simply because the dimensions available would not store the required quantity of fuel. There is simply no evidence nor any compelling argument that would indicate you actually would get a nuclear detonation out of the vehicle.
Even more to the point, if you assume for a moment every point I stated was false, you'd have to wonder just why people use nuclear weapons if they have such a pitiful blast radius. A human can stand against the blast at a few dozen yards without injury afterall.
Personally, I'd conjecture that what you see is not, in fact, a nuclear detonation, but rather an explosion of some other component in the vehicle that spreads a quantity of fissile material about as a result. This provides a better explanation in general.
Of course, the real logic problem in play is we know the Great War was fought over petrolium resources (that is, afterall, why China invaded Alaska. Once the reds were defeated there, a counter-invasion of the chinese mainland eventually triggered a full scale nuclear exchange. This is after a number of local exchanges in the middle east after oil ran out there). Since we know that nuclear technology had reached a state such that virtually every vehicle in America had a nuclear reactor powering the whole thing, and fission batteries and the like were commonly available as well, why were we fighting over oil at all? Seems like we might have moved past that particular problem doesn't it?
