Drivers Licenses vs Driverless Cars

The recent revelation that Google is applying to allow driverless cars on the road in Nevada combined with the stink over E-Verify (the backdoor National ID attempt) and its collection of drivers license data ala REAL ID got me thinking.  What happens to the identity infrastructure in this country if drivers and necessarily drivers licenses go by the wayside?  It has always been a pet peeve of mine that drivers license have become the defacto identification in our society, because so many people have them and must have them to drive.  Its a classic case of mission creep, where drivers license, which once were solely issued to display that the bearer had a license to drive (i.e. met the minimum standards) but now are used in all sorts of scenarios to verify identity.  In the future it seems, people might not need this ubiquitous item.  Its quite possible that most people may just transition to state issued ID cards, but it is interesting the pontificate on the alternative.
