LTTW's revolutionary France is primarily based on exaggerating OTL revolutionary France into the larger-than-life image of how it was seen through contemporary British eyes. In particular the rise of French nationalism based in part on paranoia and resentment about the role of powerful foreigners in the ancien régime. Similarly the use of high technology in the sense of 'the dark light of perverted science' (to quote Churchill) for the Cugnot wagons, the phlogisticateur, etc. is similarly inspired by an exaggeration of the use of spectacular technology by revolutionary France such as the Aerostatic Corps at Fleurus and of course the Chappe semaphore network. Which in OTL led to paranoia by France's enemies that France was going to pull some terrifying new technology out of its pocket to, say, invade Britain.I mean, wasn't that why you made Revolutionary France a steampunk Nazi country? I do like the Jacobin Wars section of the TL a lot, and found it quite entertaining, but I didn't understand why Revolutionary France suddenly held opposite views to OTL. I mean, sure, Linnaeus' racism had more clout than OTL, but that doesn't necessarily mean that Revolutionary France turns racist. And as for the steampunk part, how did Cugnot's highly inefficient cars become such an effective tool for France? Seems like Rule of Cool is in effect here.
The reason why the Cugnot wagons are a more realistic weapon of war, by the way, is that Cugnot's experiments were done in the 1760s and 1770s and their first use in war in TTL is not until the mid-1790s. That's a lot of time to refine them if he got patronage from the ancien régime to do it, as he does in TTL (and I believe one of Tony Jones' timelines does something similar).
