"Most people" (which is, in reality, "most of my geek friends with high disposable income") shifts to "everyone" by the end of sentence. Also, my devices seem to know where I am...within a few city blocks: I do not like your requirement of always-on mandatory tracking, both from privacy and battery life POVs.
Even worse, this has major false negatives: it's not a probation tracker device - if I leave it at home, am I now fair game for AVs? And even if I have it with me and fine position is requested, rarely do I get beyond "close to a corner of X an Y Street," usually the precision tops out at tens of ft: worse than useless for real-time traffic detection.
Moreover, your proposal for car-only roadways is only reasonable for high-speed, separated ways; I sure hope you are not proposing fencing off streets (as would be the case here: 50 km/h > "a few km/h", this is the usual city speed limit).
OK, it was a dumb idea. Mostly dark humor. Reflecting my concerns about smartphones etc tracking location. But I do see that GPS accuracy for smartphones is about 5 meters,[0] which is close to being useful to alert vehicles to be cautious. And yes, it wouldn't protect everyone, and would probably cause too many false positives. And it's a privacy nightmare.
Some do argue that speed limits for unfenced roadways within cities ought to be 30 km/h or less. And although fatalities are uncommon at 30 km/h, severe injuries aren't. I live in a community where the speed limit is half that. But there's no easy solution, given how prevalent motor vehicles have become. Except perhaps self-driving ones.
