Will 5G be necessary for self-driving cars?

Proponents of 5G say it will offer ultra-fast connections, speedier data downloads, and be able to handle millions more connections than 4G mobile networks can cope with today. One use for 5G is self-driving cars, but will they really need it? The telecoms industry envisions autonomous cars equipped with hundreds of sensors collecting and receiving information all at once over a network. It calls this concept "Vehicle-to-everything" (V2X). To achieve this, the car needs to detect blind spots and avoid collisions with people, animals or other vehicles on the road.
