I don't agree, and largely because you don't have a 'right' to drive within the United States, which is likely where they'll draw any legal help for challenges within the US. You also have limited rights in public places. What's the difference between a black box in the car and investigators measuring your travel speed using a camera from a gas station across the street? Or even in the same parking lot?
I'd say about the same difference between unmarked cars following your car around 24/7 and a GPS tracking device.
Yet the Supreme Court unanimously found that there was a significant difference in that scenario; that the later required a warrant (while the former didn't)
Sometime technology makes something so easy or so covert to widely accomplish that it, in practice, makes it effectively a change in kind not just degree. When that happens laws are written, or courts can find, that because something has become far easier to do that additional protections are required to maintain an acceptable level of practical freedom.
