I'd only want an estimate of the travel times between destinations, not an estimate of how long I'd actually spend stopped at each (which I wouldn't attempt to estimate in advance anyway).
For me the use case is this: I want to drive from (say) San Francisco to Denver, and want to plan out a schedule which involves stopping every two hours for a break.
