It seems like camera or radar systems at intersections would be easier for advanced warning of someone running a red light than having to fit every car with a radio that broadcasts its speed etc.
Apart from that, this is a concept that's a long time coming, but assuming it can be made sufficiently anonymous and optional, seems like a good idea. Like maybe cars should only broadcast a random percentage of the time so that it doesn't look weird for a car not to be broadcasting.
Interesting tech, but why not (also) broadcast this information to displays to the side of the road or above it? Much like some other warnings are already displayed on highway signs about black ice, accidents and a whole variety of other hazardous conditions.
Focusing on "smart" cars does come at the detriment of drivers and passengers of older cars who do not receive these warnings, and means that only the drivers and passengers of modern vehicles benefit from these alerts. Even putting aside from the obvious fairness issue of such a system, what good is it if only a fraction of drivers can be reached?
Public safety alerts should not be limited to a limited group of people who could afford the latest tech.
Note that the stock photo in the article is not an accurate depiction of the road this system is being installed on in Utah. The photo is of a long interstate, while BCC is a tight, twisty and technical canyon climb beloved by local bicyclists, car enthusiasts and motorcyclists.
