ALPRs are everywhere these days. "Very common" is probably understatement in this situation.
"very common" has no standard meaning, so the statement is meaningless either way.
I can’t find anything stating this is “very common”. I guess as a rough metric for “very common” let’s say on a similar level to heart attacks. Quite rare still but common enough that you could be justified in calling it very common.
So 850,000 cases per year.
