I don't know about those other things, but driverless trucking isn't going to happen within the next 50 years at least. Besides all the logistical challenges and risks to businesses throughout the supply chain, you're talking about 3.6 million American truck-driver jobs. There is little else that politicians love more than saving jobs, especially blue collar, and that's a helluva lot of jobs. To put it in perspective, the TSA is basically a jobs program that costs 12 billion to employ only 58,000 people who don't do anything useful. Politicians'll do whatever it takes to keep those 3.6 million jobs. Add on the fact that truckers can and do organize, and it doesn't take many of them to shut down shipping and transportation. The trucking industry is also reticent to upgrade or spend more money; they won't even invest in electric trucks with drivers. And there's a wide variety of trucks out there with complex routes that won't be mapped, so only a few major highways will be covered, meaning you still need a driver. There will be pilot programs but that's it.
