True, but it is still simpler to think in terms of countable/non-countable. Yes, cars is a plural noun and traffic is singular. But I have three cars in my driveway. Can I find three traffics on the highway?
Snappy, technically, you have a point (a good one, actually). In this sentence structure I would say that "novels" is idiomatically preferable in both sentences, but the second sentence would be grammatically correct. In a different structure (Any novel by Austen is worth reading) then you could definitely follow "any" with any singular noun.
The best way ist to say: with ending -s we use many /few and without (except people, wo/men and children etc) we use little / much.
