You asked about the necessary resolution. See this picture:
This was taken from about 4 metres, with a resolution of 4128 × 3096, and neither of us were moving. You have no hope of reading the number plate from the image. The plate was covered with dirt road dirt left over from slush that had been thrown up (we were just below freezing today so the snow was melting a bit.) The person sitting beside me had a slightly different angle which put the letters into a little more relief and so was able to barely make out the plate, with some uncertainty about the letters; I had to change angles to see the letters myself.
Therefore, in some conditions even from close by and no movement, 12 megapixels is not enough. But if the plate (and our own windshield) had been clean instead of slush-covered, then I am sure that 1 megapixel would have been more than enough. This is why talking primarily about resolution is pretty much the wrong question.
