With a straight face, I expect that it is too expensive for the police department to hire a human to stand at every highway on ramp and offramp, and to write down every license plate of every car that drives past them, and then furthermore for it to be infeasible for them to pay a human to search those records and replay every place I've been, for funsies. If I'm Al Capone, that level of effort is warranted, but to be able to do that for everybody and backdated too? Yeah, not OK. Historically, it has not been possible to do that. That technology makes it possible for that to be possible should be balanced with the fact that it wasn't remotely practical.
