You literally have to 3D map roads. Then upload that data. Allow cars to download that data, and upload updates (road closures/constructions, new potholes etc),

You literally have to 3D map roads. Then upload that data. Allow cars to download that data, and upload updates (road closures/constructions, new potholes etc), telemetry etc. Control will not happen over 5G, but the volumes of data being passed around certainly will likely require a good amount of bandwidth. Do you see this happen over LTE? Idk. maybe its not cars, but simply a much better surveillance system somehow.
