The funny thing is that disambiguation of glyphs in a font is a solved problem. Slash the zeroes, wide serifs on the capital i, etc. They just...don't do so in these states where it is still a problem.

It's also a a problem because not all states are the same, some don't allow O, some do. Some allow 0, some don't! The cameras need to be able to read both.

		In the UK this issue was recognised decades ago. They only allow certain letters and numbers in specific places on the registration plates.
