Now, it's possible people drove 40s cars in the 50s. But the whole neighborhood? Everything is 40s there. It doesn't make sense overall for any of it to be in our timeline. There has to be alternate timelines. But even that wouldn't make sense, UNLESS Old Steve jumped back to our timeline with Quantum Realm tech after Peggy died, bringing with him alternate timeline shield which he then gifts to Sam.
