What about the tech they already achieved by 1944?
The Schwalbe is one thing, and it actually served and led to the proliferation of jetfighters.
Die Glocke is well known too. Not what it was (a nuclear-powered magnetic repulsor drive testbed), but its existence is.
As for the power source, it's also fairly well known that Germans were developing nuclear power in Norway, and rather critically the spec ops reported that it wasn't for the proliferation of nuclear weapons; the focus was strictly on compact high-density power stations, the sort you can fit inside a ship, maybe an airship/plane, maybe even a tank.
That leads to the German experimental submarines, some of which were lost and never found but were prototyped to stay submerged for 9 months at a time.
You can't do that without a nuclear power source.
Interestingly, nuclear submarines were the immediate focus of the Americans after the war.
But let's stretch it out a bit. Americans experimented with nuclear cars too. Ford designed one, they may have prototyped the concept but nothing was ever completed officially.
Germans would've made nuclear cars and they'd have worked. You only need 100kW to get a car to do 70mph on the autobahn, reasonable for 1945-1950. A little nuclear reactor can power that and it wasn't out of reach.
They'd probably even take the Tesla approach and implement wireless power. Yeah the man, not the company. With it you can have a receiver with a switch in series (so you can turn the device off) and power whatever's on the other side.
You see the thing about Germans is that they love ideas, and obsess over doing them well.
I cannot imagine an American flying car airway infrastructure with altitude and FAA shit, but the Germans could pull it off.
They won't even need an AI to prevent the crashing.
