Keep dreaming and buying into whatever fantasy rich people keep selling. Hyperloop isn't even a thing and neither are driverless cars. Even if we get fully automated cars the roads will stay congested.
I get the feeling driver-less cars are going to be a thing given all the money. I do wish we could have some standards for "annotating" the roads with useful beacons to help things along, but the money is probably going to talk. If driver-less cars appear, I do expect roads to flow a bit better just because of proper grouping and better coordinated exit / entrances.
Yes, the Hyperloop is pretty iffy, but at least it won't conflict with freight rail.
