Foothill Transit line 669 is a "long" distance line that does not make frequent stops. It primarily runs on the I-10 freeway. These "long" distance lines generally speaking never see standing loads.

WB only has 2 loading stops (originating and one more) and either 3 or 4 drop off only stops including the termination. EB is reverse with 3 or 4 pickup only stops and 2 drop off only stops. 2 of those pickup/drop off only stops are right on the I-10 busway. 1/3 of the buses terminate/originate at Union Statin the other 2/3s have 2 stops down town LA.

So to those complaining about start/stop jerkiness and the number of doors, next time try doing your homework first before opening your mouth and inserting foot.
