"Announced at CES 2019, Ford Motor Co. plans to roll out C-V2X wireless technology, that will augment sensors used in its proposed autonomous cars, making the view from radars and cameras more comprehensive. The new technology enables sharing data, such as car's location,the color of a traffic light, road signs and pedestrian's crossing, with other vehicles.
With high-speed 5G networks available at the time, C-V2X, if fitted by other vehicles and city infrastructure, can significantly facilitate the development of smart cities. However, costs of installation/maintenance for budget-constrained governments and requirement for pedestrian's to be carrying smartphones to receive/send signals could prove to be burdensome and unreasonable." – Vinay Piparsania
