What would be most effective would be a pair of rules in tandem:
1. Allow the location data to be utilized by the cellular carrier only for legitimate engineering purposes relevant to the delivery of the cellular services. (The network needs to know your location in real time in order to route calls to you.) Also, allow the use of real time location data for emergency services in response to an emergency call. Potentially also allow the use of emergency services initiated real time locations, with a non-suppressible UI required to be presented to the user if this is performed.
2. Require that the cellular service providers purge / NOT retain this location data for any longer than is literally required to provide proper service.
The data retention policy #2 item here is essential in preventing temptation to come up with end-runs for the first rule. It's important that historic data that has no legitimate use under rule #1 not be preserved so that there isn't a mound of accumulating data of theoretically increasing value if only we could change / get rid of rule #1. That sort of thing will create ever mounting incentive to repeal / replace rule #1.

At least for GSM, that isn't as true as you say it. It only needs to know in wich group of cells you are, as as re-registering with each cell change was deemed too heavy on the battery, and they rather page for your phone in the entire location area.
Likewise, triangulation requires the phone to send something, which means that you can notice that, and also that continuous triangulation will drain your battery.
(Which brings up the question of how often and how smartly google sends updates for the traffic density map.)
