Filter out transit directions in the red states

I  like the fact that Google Maps gives me transit directions, but that's when I'm in New York.  In Norman, it is just ridiculous:

I searched for a glass shop in Norman, and Google helpfully pointed out that it was only 0.3 miles from the Amtrak station.  As if  any one could use the once-a-day tourist train to Fort Worth for transit.

Machine intelligence is all well and good, but Google needs a red state filter.
