You can leave your house in San Jose and be at your destination in
Sacramento faster by car than you can by going to the airport, arriving
early for security, standing in line, finally flying the short flight,
then
driving back into Sacramento. Probably the same for almost any trip under
say 300 miles.

Even assuming your time estimate is valid, it doesn't preclude a viable
airline route.

Here in the Pacific Northwest, we have airline service between Portland and
Seattle (~200 miles), Vancouver BC and Seattle (~150 miles), Bellingham and
Seattle (~100 miles), just to name a few. I won't even bother to mention
the numerous cross-water routes that are short (30 minute flights, or
shorter) but viable because of the lines at the ferries, and the time the
ferries take.
