Look at it this way. How much is it worth to law enforcement? If a guy doing traffic enforcement in my jurisdiction sees me bragging that I drive to work at 120 km/h in a 100 km/h zone online and that I have a GPS recording everything, which is he more likely to do? Is he going to bug his supervisor, go to the FBI to get a warrant to get the server logs for BITOG to prove where I am and my identity (even if I were to disclose it online), get a warrant here to get my GPS data, then get me in court, then prove to a judge beyond a reasonable doubt that the GPS data is accurate (considering I doubt it's ever been done in this province or even this country), and that it was me driving the vehicle, all for a $150 fine? Or, would he, maybe get a little more information out of me and simply run radar and zing me coming home one night?
The former has so many flaws and holes in it that it isn't even funny. The supervisor would flip, and I wouldn't want to be the one phoning the FBI for a search warrant for an American server for a speeding charge. In the end, I could also be boasting and never exceed 80 km/h in a 100 km/h zone.
If I did a Youtube video of me drinking and ripping around town, endangering lives, but that's another matter altogether. Law enforcement doesn't have the time, no matter how much technology is there to help them.
If even 10% of people who got tickets insisted on a trial, rather than pleading guilty by mail or in person, the court system would grind to a screeching halt.
