Technological advances, upon technological advancements, one could simply not fathom the degree to which the German Reich had not only shocked their enemies on the global stage but also their allies.
Armored cars were one thing, they had already been developed by nations and deployed as far back as the Italo-Turkish war of 1911. And sure, the ones used by the Germans were far more advanced in pretty much every way. But going against such vehicles was to be expected.
The same could be said for military aviation. Were the German planes significantly more advanced than their adversaries? Most certainly, but given a few years of development, this gap could reasonably be closed, at least to a certain extent.
