The number of teenagers with driver's licenses is the lowest in history. Compound that with the 65+ cohort aging quickly, and older drivers being dangerous drivers (lower reaction time).
It's not a convenience delta. Its an experience and safety delta. We are talking tens of billions (if not more) of dollars in savings from taking the human out of the loop.
The value of such a statistic is questionable given that the minimum age for a license has increased of late.

That said, this is going sideways because I didn't make a complete and clear post originally. Never mind.
