How 5G connectivity and new technology could pave the way for self-driving cars

Hybrid peer-to-peer/5G vehicle communication technology, C-V2CX ("cellular-vehicle-to-everything"), has evolved since it's 2016 debut, with recent demos showing how it helps vehicles "see" threats and obstacles out of sensor range (such as cars coming around corners, traffic lights and so on). But it's not the only protocol on the block – Toyota, the world's largest car manufacturer, and GM, prefer a competing protocol based on wifi. The winner should start to emerge later this year when 5G trials begin.
C-V2X enables vehicles to communicate, which should reduce accidents and aid autonomous driving.
