I read up on this [0]. It looks like it helps to have a newer phone, and even then this feature is inconsistent across models, with some phones spewing non-random frames even when wifi is off and/or depending on how location services is configured. Although I would assume the feature will continue to be better implemented as time goes on, it doesn't look like something that is protecting most people yet. I read a bit about bluetooth tracking [1]. Apple and Google both apparently support this kind of tracking via apps, and a lot of apps use toolkits made by advertisers that do this. Apple has been selling their iBeacon devices that can be located in stores to track people. Here's [2] something about google tracking via bluetooth even when bluetooth is turned off.
