I don't see the point of unpredictable routes. If they decide to arrest you they will knock on the door.
Physical tracking builds a profile you can’t see but they can search anytime. And when they decide to use it, you don’t get to argue the context, just the consequences.

True, once they have decided.
Unpredictable routes throw off physical surveillance whether it is feds building a case, the local toughs trying to decide if / when / how to rob you, or that violent ex-husband who is watching trying to determine when the kids will be home alone with the 16 year old baby sitter so they can snatch them.
There are endless threat models that don't involve warrants.
