You do know that war wagons and barricade wagons were not a Hussite invention, right ? Because saying otherwise is like peddling all those typical memes about the katana being teh best sword in history evar. Barricade wagons were used as early as the 6th and 7th century, by Germanic and Slavic nationalities alike. And war wagons in the Hussite sence (arguably the earliest example of a
technical) were developed independently in several parts of Europe during the High Middle Ages. It's just that central and southeastern Europe kept them as a military tactic the longest. They were used regularly in Hungary by both armies and revolting peasants until the Dóža Uprising of the 1510s. After that, they were only used as an occassional solution, since their heyday was mostly over by then.
The thing about Hussites, war wagons and wagenburg formations is that they perfected them as a military solution/tactic. And the secret to Hussite successes were not just the wagon-related tactics themselves, but also related military tactics, developed with subterfuge and effective travel times in mind. The Hussite armies were among the first to march and tow their equipment even during nighttime, which was fairly uncommon for most armies back then. But it gave them a much needed edge over those underestimated "rapid deployment" travel, as tiring as it was.
And also, the Hussites weren't exactly obsessed with chivalry. They were pragmatic late medieval warriors to a fault. Hide in the wagenburg, defend it like a fort against attackers, then send out some medium cavalry and heavy infantry to mop the attackers up once they rout.
