None of that is true. You can only legally be issued with a traffic fine by either a police officer or one of a very specific set of devices (certified speed/red light cameras). It is not possible to get a fine by installing an app or whatever or participating in this study. Second, QUT isn't an arm of the government, but they absolutely are bound by the Privacy Act. They couldn't give this info to the government without your permission if they wanted to (which generally universities don't, because they actually want people to participate in studies...)
1. They're not going to change the law to allow uncalibrated devices to issue infringements. Practically every single one would be thrown out by a magistrate. Loosen your tinfoil hat.
2. Council officers can only issue stationary vehicle infringements (i.e. parking). They cannot issue speeding fines, red light fines, or any of those things.
3. A court order must specify exactly what is being ordered, and why. A court order for "everyone who was speeding" would be unlawful, and be declined. Again, loosen your tinfoil hat.
4. The commercial sector is largely unregulated. The government, however, is not. I can tell you right now without a shadow of a doubt that neither the police nor the transport department have anywhere near the level of access to data that you seem to think they do.
Accusing someone of having, or wearing, a tinfoil hat does not mean that their concerns are unwarranted.
Actually uncalibrated, or perhaps I should say “calibrated by decree“ devices are allowed now. A policeman can issue a fine based on his estimate of the speed. They might be good at it, but they most certainly are not calibrated. In any event, the need for a calibrated device can be negated by the way the law is written. As any smart car would be using GPS, it’s probably hard to argue that it isn’t calibrated, to well beyond the level of most instruments.
Police, transport departments, or anyone else for that matter, will have whatever access they are given by the government. There is nothing fixed in that particular goalpost. The fact that our government has been leading the charge to breach cell phone encryption, does not make me feel that they would treat car data as anything other than a treasure trove.
I’ve lived for the vast majority of my working life, with flight recorders monitoring every detail of my flights. Whilst they were fitted in an attempt to improve safety, numerous jurisdictions around the world treat them simply as a source of information for police prosecutions. Any system can, and will, be subverted from its advertised use.
I have a car which already has this sort of technology. The level, and detail, in the tracking is quite amazing. I see no reason for any department to have anything like that.
