Five years ago, any discussion of 5G included a vision that we’d end up with smart cars that were all connected with a ubiquitous 5G network that was going to be built everywhere. We’re still waiting to see a real 5G network anywhere instead of the 4G LTE networks that are still being touted by every cellular company as 5G. The idea of a ubiquitous network capable of supporting smart cars died, but there is still an effort underway to use wireless technology to make car travel safer.
