SCOTUS has already ruled that tracking people's movement over time without a warrant is a Fourth Amendment violation.
Unfortunately, “SCOTUS previously declared this unconstitutional” doesn’t have quite the same sense of finality it used to these days.
No, the court ruled that people have a reasonable expectation of privacy in their cell phone records. You're going to get to some weird and inoperative places if you try to generalize from jurisprudence like this. You do not generally have an established right to move without being observed in the US; the very fact that you're required to keep a clearly visible tracking device on your car or motorcycle shows that.
The current SCOTUS likely doesn't care about that.
Fascism is coming, and we're the slowly boiling frogs.
Why would they care lol
Until SCOTUS rules that parallel construction is a constitutional violation, the FBI is free to track everyone and build cases from illegal data.
