This wouldn't necessarily indicate the vehicle being used or its owner/registrant for tax purposes. Additionally, mobile network triangulation isn't usually as accurate as GPS or other satellite systems.

Not knowing the answer I just read 3 and a half page. It seems the Dutch police only obtains location data in real time and only when someone is a suspect.

But do the mobile networks keep a log, and can those logs be subpoenaed anytime?

I assume all protections can be dismantled in the name of “security” or a “terror threat”, even in the Netherlands.
