It doesn't sound like they were reviewing the cars, only the driver assist system.
A proper analogy would be the Ford getting 8/10 on it's breathalyzer, and the Porsche not receiving a rating, since it doesn't have a brethalyzer.
Not being able to drive on many roads that haven't been loaded into a database does not sound like it drives on roads better to me. If they are testing the driving feature then Testla wins. If they are testing the driver nanny feature, then Cadalack wins and Testla gets no rating, since it doesn't have a driver nanny feature.
I would guess that the problem with using facial recognition evidence in prosecuting "minor" crimes is that the accused might fail to put up a legal defense, because they cannot afford it, so people can end up being criminalized unjustly.
You are assuming that the police will tell the accused that facial recognition was used. From what I have read that does not happen. How do you prepare a defense against something you do not know is being used against you.
