The US has already automated all of that. There are vey, very few automation efforts that need the low latency of 5g. For example control system scans for Utilities are 3-5 secs. Automated metering data are cached and only need to be sent at 5 minute intervals. IoT connections are $1-2/month. Automated cars and trucks need precise GPS and collision avoidance but no cellular connectivity, unless you want to stream audio and video. There's an effort to utilize Cellular V2X over LTE but the technology is way ahead of its time. Let's get the autonomous driving part down before we use V2V or V2N. Plus those applications can be just accommodate by IEEE 802.11p a short range comm protocol.
I actually stumbled on the affiliate agreement tonight in edgar (I was surprised to find it). Note what goes into the calculations on 11.7.2 and 11.7.3 and especially what doesn't in 11.7.3 (e)
