Do you see self driving vehicles being operational soon?
I can imagine a time based exclusivity to the outside lane on expressways.
From 10:00PM to 6:00AM for autonomous HGV's to trundle long distances without drivers. It would require the investment of depots for the loading /unloading containers. Only really any good for mid-distance 300-500 Kms that can replace rail.
As for urban car's - it may happen but not any time soon.
