... which is done as a matter of course in many countries. Hell, the Netherlands does this for all cars, always, "to send speeding tickets". They are scanning and identifying all cars, whether or not they have reason to suspect anything.
This will be a constant in the future. It has everything government wants : a gross grab of power, vast potential for abuse, and it saves a little bit of money ! What more could you want ?
Not necessarily. The cameras the roadmanager (rijkswaterstaat) use to view the busyness of traffic are still out of reach for law enforcement. They could use those cameras for a whole lot of more money if they were allowed.
Weird, I've read in the news multiple times that these cameras "accidentally" caught some sort of criminal. From people wanted by the Dutch IRS to people "running from youth services". They were particularly proud of catching those people running from youth services when they ran unannounced, and before they hit the border.
You see, apparently youth services has a problem that once across the border all the "crimes" like having a teacher pissed off and report you to youth services or having your parents divorce, which according to the Dutch should lead to a child's incarceration are not actually crimes once you cross the border. You see, they feel the need to increase the safety feeling of children with divorced parents, by having the police violently (search on youtube) abduct them, then dumping them locked up in a "group", ie. a set of adults who don't care about them at all (not professionals, of course, those are expensive. No, the normal people they come in contact with come without so much as a high school degree), with total and complete power over them. But then night comes, and those adults abandon the group entirely, so the kids are totally at the mercy of older kids or just the more violent kids in said group. Needless to say, the rate at which rapes and sexual assaults happen in this environment is "somewhat" higher than in normal society. Oh and why does the Dutch state do this ? To make the child feel safe ! Sadly, that's not a joke.
Sadly, if you were a lawyer, you are now to advise that if you're trying to keep kids away from those services, you need to either rent a car (not sure if they surveil that yet), or you need to physically assault the police (you laugh, but that's exactly what immigrant communities are doing in Rotterdam and that's (granted, a small part of) the reason why they're doing it. The alternative in some cases is giving up their kids to these monsters. Again the government responds, not, of course, by fixing their own problem).
Because of these sorts of things, most of the neighboring countries have become appalled at this behavior and refuse to cooperate in all but the worst cases, so naturally they're fixing it : the fix for that problem is employing high pressure tactics to get other police forces to cooperate and mass-surveillance on their own people.
