The baseline expectation of anyone operating heavy machinery in public should be that it is tracked for safety and accountability. This is a good thing. We've been installing tracking numbers on them for decades, what did you think they were for?
I understand for many people, their movements and their vehicle's movements are 1:1, so it can feel like tracking their vehicle is tracking them. If you care about privacy, travel without the heavy machinery. Walk, bike, transit. If your region does not allow you to do this, direct your privacy-related energy towards making that possible, rather than reducing accountability for drivers.
Edit: I wonder how the commenters below feel about tracking jets, probably similar to how I feel about tracking their cars.
