As to using a smart phone instead of a GPS, how does that prevent someone from getting your speed and location data?
Well so far, the phone companies are pretty good about requiring a warrant, and they don't sell it on their own.
Crash is right on the money there. Cell phone companies are very good about making things difficult for us without a warrant. They have entire divisions that deal with subpoenas and warrants and each phone company has a certian set of rules that we have to follow. Most times it's a pain, but at least I know they are protecting my data also.
However...You should see the amount of data they keep. HOLY ****...Two years ago, we went on a tour of one of the bigger companies data storage facilities. I don't even remember the numbers, but the amount of data they have coming in there per hour is astounding.
The reason they want warrants is to limit their liability from customers suing them when data is given to law enforcement. I would think that if Garmin or TomTom was taking data from GPS units plugged into computers, they would fall under the same liability issues. I know I have to log into my Garmin account when I do things with my GPS units. I'm assuming TomTom is the same. Hell...event taking that data directly from the GPS when it is mounted to your windshield may hold liability issues.
I just donno if the claim that TomTom is selling that data is true. I don't live in Europe, so maybe, but I know here in the states, I have never heard anything like that going on. We get most of our data from crash reports, issued citations and those little "Your Speed Is" speed trailers that display you going by at light speed just so you can see it flash. The RADAR unit inside there downloads data including number of cars, time of day and speeds to a spreadsheet and we use it to figure out if recent enforcement worked, needs to be done, or isn't necessary.
Please also remember, a speed trap is not a bunch of cops enforcing the speed in an area. A "speed trap" is 'artifically lowering the speed limit in an area for the purpose of increasing violations.' As far as I know, speed traps as described above have been illegal here for years.
Eihther way, even if Garmin was selling my data, I donno if I would care...But I'm not sure.
