There are a couple of well know images taken from an SR-71 travelling at 80,000ft @ M3 over IIRC a football stadium in Kansas...you can clearly see the lines used in the car park to mark the individual spaces... those lines are 3 inches wide...
I think the camera in the U-2 was the same...
The A-12 (the CIA Blackbird, singel seat which started the series) had a different camera as its primary sensor which was 'apparently' even more sensitive....so perhaps that is why the reading number plates rumour/myth came about..
Even so 3 inches from 80,000ft and M3....pretty impressive.
