Roy is a trucker who's looking forward to 5G. Leo says he won't see robust 5G for a few years at least. It'll be spotty at first, and companies like Apple won't support it at the very beginning. Roy is also an expert on self-driving semi trucks. Leo says everyone is terrified of a massive 18 wheeler driving itself down the highway. Roy says that the US Department of Transportation is going to require extensive testing before certification. And it will require a safety driver. But ultimately, the trucks will be completely unmanned. And that's going to put a lot of drivers out of a job.
