We can’t even standardize on a format across browsers without severe inconsistencies and bugs, yet you expect vehicles of all types and pedestrians to cooperate in a network? That’s not even taking into account the outliers who refuse to conform (or worse, those who try to hack it).
Every car has plenty of communication and localization systems today. Nearly every pedestrian carries an electronic device with potential for exact localization. It makes no sense to not use that data, and solely rely on still-not-perfect computer vision. The optimal system will necessarily be a combination of both.
As for standardisation, maybe realizing what an enormous number of fatal and many more forever life-altering accidents we currently consider normal will finally get people off their backsides. I wish somebody would start a media project revealing how insane the current situation is..
Wanting/needing something to work and it actually working is two entirely different things. Again, refer to my point about browsers. Happy to give a lot more examples if that's what is necessary.
