Sounds like a "bad" thing for them to do, from our perspective. But what if this actually caused those drivers to drive below the speed limit. On some level, this just easily solved a problem that's been plaguing city governments for decades if not a whole century. They've tried fines, tickets, speed-cameras, traffic-stops, police presence on the roads, etc. An entire industry has spawned off to cater for all this "societal fluff" of trying to get people to not do things by metaphorically "spanking" them. And here we have a semi-reasonable solution to the problem that's cheap, self-enforcing, and all it requires is for us to have some level of trust for the tracking devices/data/company.
