Why do you frame it as a decision between the two? The market is beyond huge, there are bound to be use cases where one or the other is clearly better. Also a 10x cost improvement on nuclear would blow everything else away (in a good way). I don't think renewables have the same potential - for one thing, they're a more mature technology (weird, I know, but they've been the focus of global development for quite some time now). And also there's only so much energy you can get out of solar and wind - you just can't get more than 1.3 kw from a square meter of solar, you have to cover more square meters. On the other hand there's no theoretical reason why you wouldn't have a clean, safe reactor in each car. It's just a technological challenge.
