Do you know if there are datasets with pseudonymized LPR data available? I'm not interested in the actual license plate obviously, but being able to so say that two data points are the same car would be extremely interesting data especially for these larger and larger datasets spanning longer periods of time.

I'm also aware there is still a bit of a privacy concern with that type of data but honestly don't really have the math background to know exactly how that occurs or the extent to which you can minimize it.
