This is the sort of idea that looks great on paper and simulations but that totally falls flat in the real world. The system would require trusted communication. The system would also have to cope with any number of vehicles not having this feature or with broken/defective feature... What's the fail safe solution? To rely on traffic lights and priority markings.
