That's what I was thinking. You can see in one photo on the article that the O is squared off, and the zero is rounded, but it still seems ripe for confusion.
Yeah this is a problem even without technology. I believe the UK does not use the letter O in standard registration numbers so it cannot be confused with 0.
I believe, in my state, similar looking characters are considered identical for vanity plates. I assumed this applied to state issued plate IDs as well, but maybe not. It's hard enough trying to read a license plate on the road without throwing in confusion over B vs 8 and O vs 0.
