Reminder: Turn off location services/GPS systemwide to opt out of these databases. The subscriber location tracking performed by cell towers is much lower resolution.
Disclaimer: Work at Google, but opinions are my own.
* They would not of known where to place it before the crime took place.
* Even if they somehow got the data about the location of the cyclist under the table they would have had no way to parallel construct anything.
Since there was no other evidence that would of been it.
This is not a new thing. The authorities can open and read your mail as much as they want using bamboo splints and/or the steam from a kettle. But because it is very illegal to do that it greatly reduces the abuse possible from such actions.
Privacy laws are a prerequisite and are essential.

I bring this up to say, Faraday cage and leaving the phone behind may not even be enough with a sufficiently large surveillance state.
Edit: leaving the phone at home is different than a hotel, of course. But even that might raise too much suspicion unless you frequently, and randomly, leave it at home. That way the lack of movement wouldn't necessarily indicate you didn't want to be tracked at a particular moment.
How about a real-time analysis of all security camera footage and everyone's photos and videos, using face recognition and other techniques (movement, clothes associated with a person etc.). Cars are tracked via license plate, if they are not online now anyway. You pay cash but "they" know the serial number of the bill the ATM gave to you and which shop owner gave it back to the bank a little later.
There are probably many patterns that are only known to people who do this kind of thing full time. Maybe there is a very small number of people who buy the very same two items at a gas station. If Amazon knows who's pregnant early, some will know who's trying to go private and why before they know it...
I agree with you. I think, at some point, the only way to go about doing this without inducing insanity is to get someone on the federal side to tell you what tools they have at their disposal so that you know exactly what you're fighting against. Otherwise, you'd drive yourself crazy with tinted windows, license plate switchers, randomized purchases, Faraday cages, and more.
Check traffic before you depart, pick a route, and leave some extra time in case you hit unexpected traffic.
I know I've been going on about it lately, but for almost every "How can we possibly do this without an app tracking every bit of data it possibly can?" sort of task, people were doing that, or something functionally equivalent, before cell phones, or on cell phones that aren't actively user-hostile.
Yes, I carry and use a smartphone. But it's a convenience. I don't need to reach people or have them reach me wherever I am. I don't need GPS at all times. I don't always need instant access to information.
Google isn't going to be running some inference algorithm to identify your most probable location or residence, they are just going to give LE the raw data. Unless you are a extremely wanted criminal, LE probably doesn't have the resources to do extensive analysis of google maps searches and a jury is not going to interpret those results the same way they would of actual location history.
